Multiples of 27 have ...

The factor of 27 has

Only 54 of these three multiples of 27 is a multiple of 18, so Grandpa Xiang is 54 years old this year.

54 18 = 3 (years).

A: The baby elephant is 3 years old and the elephant grandfather is 54 years old.

Hope mine is helpful to you. If satisfied,. Thank you!

Hello: Multiples of 27 are 27,54, 81 .

The factor of 27 has 1 ,3, so 54 18=3

So the baby elephant is 3 years old and the grandfather is 54 years old.

If you have other questions, click to ask me for help after this question, it is not easy to answer the question, please understand, thank you.

Good luck with your studies!

The factor of 27 is 1,3,9,27;And the grandfather's age is 18 times that of Xiao Ming, and Xiao Ming's age can only be 3 or 9 years old.

1) 27*18 9=54, 54 18=3, grandpa is 54 years old, Xiao Ming is 3 years old.

2) 27 * 18 3 = 162, 162 18 = 9, grandpa is 162 years old, Xiao Ming is 9 years old (the answer does not conform to reality, give it away).

Baby elephant is 3 years old and grandpa is 54 years old.

Since the age of the baby elephant and the grandfather are the factors and multiples of the father's age respectively, and the grandfather's age is also a multiple of the baby elephant, then the age of the father is a multiple of the baby elephant must be a factor of 18, and at the same time it is a factor of 27 that is, 1 3 9, then it is easy to see that 1 is impossible, and it is impossible to substitute 3 into the baby elephant 9 years old Dad 27 years old Grandpa 162 years old does not conform to the reality Substitute 9 into the baby elephant 3 years old Dad 27 years old Grandpa 54 years old answer to the throne.

Solution process: 27 decomposition factors are 1, 3, 9, 27

Apparently excludes 1 and 27

The baby elephant is 3 or 9 years old

If it is 9, then 9*18=162 obviously does not match.

So the baby elephant is 3 years old and the grandfather is 54 years old.

The factors of 27 are 1, 3, 9, 27

Multiples of 27 27, 54, 81, etc.

And the elephant grandfather is 18 times the age of the baby elephant.

So the elephant grandfather is 54 years old, and the baby elephant is 3 years old.

Because Dad is 27 years old, the multiple of 27 can be found as 27 1 = 27 27 2 = 54 27 3 = 81 .........

The factors of 27 can be found as follows: (1 3 9 27 ) 4 numbers Here we can know that when the elephant grandfather is 18 times the age of the baby elephant, according to the above two sets of values, 54 and 3 satisfy the relationship Then the baby elephant is 3 years old and the elephant grandfather is 54 years old.

The factors of 27 are 1, 3, 9, 27

Multiples of 27 27, 54, 81<100

The elephant grandfather is 18 times the age of the baby elephant.

So the elephant grandfather is 54 years old, and the baby elephant is 3 years old.

The factors of 27 are 1, 3, 9, 27

3*18=54 (years)54 27=2

So the baby elephant is 3 years old, and the elephant grandfather is 54 years old.

The factors of 27 are 1, 3, 9, 27

Multiply these four numbers by 18 to get 18, 54, 162, 486, and only 54 of these numbers is a multiple of 27.

So the baby elephant is 3 years old, and the elephant grandfather is 54 years old.

Multiples of 27 are 27,54,81,108. The factor of 27 has 1 ,3,.

The elephant grandfather is 18 times the age of the baby elephant.

Baby elephant is 3 years old and grandpa is 54 years old.

Grandpa's age is a multiple of Dad's, so 27*2=54 Xiao Ming's age is Grandpa's age 1 18, so 54 divided by 18=3. Grandpa is 54 years old. Xiao Ming is 3 years old.

The factor of 27 has 1 , 3, and the multiple of 27 has 27, 54, 81 .

So 18*3=54 so the baby elephant is 3 years old and the grandfather is 54 years old.

Factors of 27: 1, 3, 9, 27

Multiples are 27, 54, 81, etc.

And because grandpa is 18 times the size of baby elephants.

So the baby elephant is 3 years old, and the grandfather is 54 years old.

The factors of 27 are 1, 27, 3, and 9, and they are all substituted to see if their 18 times are multiples of 27, so the final answer should be 3, 54 or 9,162

First find out the multiple of 27 and his factor, and then divide, and it comes out at once, the answer is that the baby elephant is 3 years old, and the grandfather is 54 years old.

The factors of 27 are 1, 3, 9, 27

Multiples of 27 have 54,81

After that, I pushed out to get baby elephant 3 and grandfather 24

It's very simple: baby elephant is 3 years old and Grandpa elephant is 54 years old.

Write out all the factors and multiples of 27, and try again, like grandpa to get 18 in addition to the baby elephant

Let's say you notify a blind person in a minute.

In the first minute, 1 person is notified.

2 3 (the first person plus the teacher's second minute notice and the first classmate's notice) can find out the above pattern, the number of macro debaters notified in the first n minutes is more than twice the number of people who were notified in the first n-1 minute1, in essence, each person who was notified before notified another person in 1 minute, plus the teacher notified 1 person.

It was concluded that a total of 2 n-1 people were notified in the first n minutes.

You are in the fifth grade, and you may not understand the meaning of 2 n, which is the meaning of multiplying n 2s.

If you don't understand, you can ask me.

The sum of the distance traveled by the two is the distance between the two places:

A is 69km per hour, and if you walk for an hour, the distance is 69*;

B is 58km per hour, and if you walk for an hour, the distance is 58*;

So the total distance is:

Let x be the distance in kilometers.

x = (69 + 58) * hours

km wish you progress!

Distance = speed and time.

69+58) km).

A: The two places are kilometers apart.

The distance between the two places: (69+58) km).

This must be right, don't worry, hehe.

When two cars meet, their respective distances are added up to the whole journey.

The method here is the same, but the calculation results are different, and you test the same.

1.Three-eighths is to divide (1) into (8) portions equally, indicating the number of (3) portions. Its fractional unit is (1 8), and adding (5) of these fractional units is the smallest prime number.

2.The unit of fraction is one ninth, the minimum true fraction is (1 9), the maximum true fraction is (8 9), and the minimum false fraction is (9 9), and there are a total of (18) nines in the sum of these three fractions.

3.The minimum false fraction for the numerator to be 5 is (5 5); The smallest band fraction of which unit is one-fifth is (1 and 1 5).

It's been a long time since I've touched elementary school math. Hehe.

1. (60+55+53) 2-55=84-55=29 (kg). That is, A weighs 29 kg.

2. Set up and transport the goods for x days, according to the topic: 30-4x=2 (57-9x) The solution is x=6 that is, after 6 days, the remaining grain in warehouse B is twice the remaining grain in warehouse A.

3. The original plan was to install x TVs per day, according to the title: 20x-15 (x+45) = 0 solution x=135 that is, the original plan was to install 135 TVs per day.

1. For convenient expression, first call A as A, B as B, and C as C

a+b=60

b+c=55

c+a=53

a+b+a+c+b+c=60+55+53=164a+b+c=82

a=82-55=27

Note that this is not an equation, just abc is used instead of A, B, C, for clarity of the process.

A: 57 B: 30

Solution: Set up to ship x days.

2（57-9x）=30-4x

114-18x =30-4x

14x =84

x = 6 A: 6 days later.

Solution: Set up a plan for X stations.

20x=（x+45）*（20-5）

20x=15x+45*15

x=135

1. Set A X, B Y, C Z

x+y=60

y+z=55

x+z=53

x=29 y=31 z=24

So A's weight is 29 kilograms.

2. Suppose that after x days, the grain left in warehouse B is twice as much as the grain left in warehouse A.

57-9x=（30-4x）/2

Calculated as x=6

So after six days, there is twice as much grain left in warehouse B as there is in warehouse A.

3. Suppose the original plan is to install x units every day.

20x=（x+45）(20-5)

Calculated as x=135

So it was originally planned to be completed in 135 days.

1.Solution: Let A be x kilograms, then B = 60-x C = 55 - B = x-5 and C + A = 53, that is, A = 53 - C = 53 - x - 5 - 5 = 48 - x = x to get x = 29 Answer: A 29 kg.

2.Solution: The remaining grain in warehouse B is twice as much as the grain left in warehouse A.

Then the equation (30-4x) (57-9x)=2 is solved by the above equation to x=6

Answer: After 6 days, the grain left in warehouse B is twice as much grain as there is left in warehouse A.

3 Solution:The original plan was to install x sets every day, and the equation could be obtained from the title.

20x=(x+45)*(20-5)

Solution: x=135

A: The original plan was to install 135 units per day.

1. Obtained from the question: A + B = 60

B + C = 55 then (A + B + C) 2 = 60 + 55 + 53 = 168 C + A = 53 A + B + C = 168 2 = 84 A = 84-55 = 29

2. After X days, the remaining grain in warehouse B is twice as much as the grain left in warehouse A.

57—9x) 2=30—4x Solve the equation to get x 15 5=135 (sets).

A has been 60

C = 55

C + A = 53

C: 84-60=24

A: 84-55=29

Already: 84-53=31

You can go to the 5th grade textbook, it will be written. I'm in 6th grade and 5th grader, but I hope it can help you.

What do you want, knowledge, I'll teach you the volume and surface area of a cylinder, or a cone [provided you have to know the circumference and area of a circle first] but you've learned where.

I'm a recent 5th grader. So I know a lot about the knowledge of the fifth grade. If you need it, I'll give you QQ.

I can teach you some topics that you don't understand. Language, English or anything is fine. It can also give you a little bit of knowledge related to the sixth grade.

Yes, the tower, the knowledge point or something.

Solution: Let x buckets leak in every minute.

According to the title, the amount of water leaking in 50 minutes plus the original 800 barrels is equal to the total amount of water pumped out by the two pumps.

800+50x=(18+14）x 50

50x = 1600 — 800

x = 16 (bucket).

A: Leaks 16 buckets of water per minute.

Total Rake(18+14)*50=1600

After water inlet 1600-800=800

The time after water intake is 50 minutes.

Water leakage per minute 800 50 = 16

(18+14) 50=1600 barrels.

1600-800) 50 = 16 barrels.

A: 16 barrels per minute.

Set x buckets of water to leak per minute.

50x18+50x14=800+50x

50x（18+14）=800+50x

50x32=800+50x

1600-800=50x

800=50x

x=16
