It's 1 4 that has gone the whole way

It's 3 4 with the whole course left

It takes 10 hours for a passenger car to travel from A to the place, and the speed is 1 10 per hour, and it takes 8 hours for a truck to drive from B to A, and the speed is 1 8 per hour for the whole journey, and the speed is the time of the distance and = meeting.

Meet in x hours.

Then: x 10+x 8+1 4=1

9x/40+10/40=1

9x+10）/40=1

9x+10=40

x=10/3

Just ask.

...I thought we were going to do the question...

1. Fill in the blank 1, denote ( )2, denote ( also denote ( )3, use letters to denote the commutative law of multiplication: (

4. 260 square decimeters = ( square meters 5. hectares = ( square meters.

6. Square decimeter = ( square centimeter 7, square kilometer = ( ha.

8. A natural number (except 0) multiplied by a number ( ) 1, the product must be smaller than this natural number.

9. Two ( ) trapezoids must be able to form a parallelogram.

10. The area of a triangle is a square centimeter, and the area of a parallelogram of equal height to this triangle is ( ) square centimeters.

2. Judgment (the correct one is drawn in parentheses, "the wrong drawing" is drawn

1. If a natural number is divided by a decimal number, the quotient must be greater than this number. (2. The area of the triangle is half of the area of the parallelogram.) (

3. The meaning of decimal division is the same as that of integer division. (4. Two triangles of equal base and equal height, the area must be equal. (

3. Select (put the correct answer in parentheses).

4. The quotient is 10, and the remainder is ( )a:92 b: c:

4. Calculation (1) Solving equations. ①

3x+2x=

2) Calculations. (If you can make a simple calculation, you should make a simple calculation).

(Keep two decimal places for the number).

5. Practical questions.

1) Write the idea first, and then list the comprehensive formula.

1. Xiao Ming reads a storybook and plans to read 20 pages a day and read it in 10 days. Actually read 5 more pages a day than planned, and can I actually read them in a few days?

It is required that you can read it in a few days, and first seek the comprehensive formula.

2) Answer the following application questions.

1. A triangular piece of land with a base of 125 meters and a height of 64 meters. How many square meters does it have?

2. A parallelogram billboard, the bottom is 8 meters, and the height is meters. If you paint this billboard with paint, how many kilograms of paint do you need to use at least kilograms of paint per square meter?

3. An engineering team repaired a canal and repaired 1,800 meters in 4 days. According to this calculation, it will take another 3 days to complete. How many meters is this canal long?

4. A and B are 840 thousand apart.

Do you want to do it or do you want an answer?

Or do you want to improve the question?

If you just want to do a review or preview in advance, then the questions in the book are very good, and you will benefit a lot from doing it well!

A pack of fruit candy weighs 1 2, and each fruit candy weighs 1 40 kg. How many fruit candies are there?

(8000*7+70000) 15=8400 (km) Xiaodong: 77 5-3 5=74 5 (seconds).

Xiaoxin: 74 5 + 1 2 = seconds).

Let B have x, and A has x+9 10

Later, A has x+9 10-1 5 and B has x+1 5, so A has 1 2 kg more than B.

Classmates, the first two have to ask.

Only the third course is a little bit more difficult.

Bag A is 9/10 more kilograms than bag B A is more than B.

Take out one-fifth of a kilogram from bag A is more than B Put it in bag B kilogram You have to study hard.

The least common multiple is: 3 4 5 60 It will take at least 60 days to meet again.

60 7 8 (week) ......4 (days).

3 4 7 is Sunday.

In fact, it is to find the least common multiple of 4 numbers.

That is, the least common multiple of 2,3,4,5 is 60

That is, it will take another 60 days to meet.

60 7 = 8 and 4, i.e. 8 weeks and 4 days, so it is Sunday.

That is, the least common multiple of 2,3,4,5 is 60

That is, it will take another 60 days to meet.

60 7 = 8 and 4, i.e. 8 weeks and 4 days, so it is Sunday.

is the least common multiple of , which is 60

That is, it will be at least 60 days before we can meet again in the Children's Palace.

60 7 remainder is 4

Wednesday is Sunday 4 days later.

The least common multiple is 60, so it will take at least 60 days to meet again.

60 7 8 (week) ......4 (days).

It's Sunday.

The least common multiple of is 60, so it's 60 days 63 7=9 (weeks), and it's Wednesday, but it's actually 60 days, so it's three days minus, so it's Monday.

Find the least common multiple of 2,3,4,5, which is 60

So we met after 60 days. 60/7=8…… 4

So for the weekend.

60 days, it's Sunday. The essence is to find the least common multiple of 2,3,4,5.

Least common multiple: 60 days after Monday.

I'm so tired, so much, you can do it first......Leaky Tomb.

So the 22nd digit is 1.

62-13+1=50 (bits).

3.Lay floor tiles on the floor of a room. If you use rectangular floor tiles with a length of 3 decimeters and a width of 2 decimeters, 160 pieces are just covered. What is the square meter area of the floor of this room?

Solution: 3 dm = m 2 dm = m.

square meters) A: The floor area of this room is square meters.

Happy learning! I'm in the sixth grade.

Addition plus addition minus minus minus) 15 Multiplicative distributive law 210 Calculate directly.

It's how many kilometers he flies per hour, and the other is how many hours it takes to fly a kilometer.

Decimeter 6 160 is equal to 960 square decimeter square meters.

==11-2

Find out how many meters per hour the bee flies.

Find out how many hours does it take for a bee to fly a thousand meters).

3.First convert the units of bricks, long meters, wide meters.

The area of each brick is square meters.

A total of 160 pieces are used, so the ground area is square meters.
