Sixth grade questions come with good grades tonight I want the answers

1.Find patterns.

Two-thirds, three-eighths, four-fifteenths, five-twenty-fourths, (6/35) The numerator 1 denominator is 2, 3, 4, 5 squared 1

2.Vocabulary questions.

Two students, A and B, walk home from school, A walks one-fifth longer than B, and B walks one-eleventh less time than A, what is the speed ratio of A and B?

B's distance is in units of 1

The distance of A is 1 5/1 6/5

The time of A is unit 1

B's time is 1 1/11 10/11

The speed ratio of A and B is 6/5 1:1 10/11 12:11

Question 1: Thirty-five molecules six.

3 is 2 squared minus one.

8 is 3 squared minus one...

Question 2. The velocity of A is x, the velocity of B is y, the time taken by A is t, then the time taken by B is 10 11t

xt-10/11yt=1/5*10/11ytx/y=12/11

1.Find patterns.

First of all, look at the numerator 2 3 4 5 is the natural number, it is not difficult to find out that the numerator of the following number is 6, and then look at the denominator 3 8 15 24 Let's use the latter number and subtract the previous number to get it.

8-3) (15-8) (24-15) is 5 7 11 is the odd number of the permutation, so it can be obtained.

The latter number (?) 24) should be equal to 13 You can know that the denominator of the number sought is 37, so the number required is 6 37

2.Consider the distance traveled by B as the unit 1, let the speed of A be x, the speed of B be y, and the distance traveled by A can be seen from the condition 1+(1 times 1 5) is 6 5, and the time taken is to divide the distance by the speed 6 5 divided by x

The distance traveled by B is 1 and the time taken by B is 1 divided by y, and the equation can be derived because B takes one-eleventh less time than A (known condition).

6 5 divided by x equals (1 minus 1 11) multiplied by 1 divided by y to give the ratio.

x/y=11/10

Thank you, if it's okay, give it points!

1.Six out of thirty-five.

The numerator is increasing and the denominator is 1 3, 2 4... Increasing.

2.Speed = distance time (v=s t).

s A: s B = 6:5 t A: t B = 10: 11v A: v B = s A s B t B t A = 12:11 I really can't knock it out. Let's make do with it.

The bottom area of the water tank is: 750 5 = 150 square centimeters The width of the bottom surface of the water tank is: 20-2 5 = 10 cm.

The length of the bottom surface of the tank is: 150 10 = 15 cm.

The length of the iron sheet is: 15 + 2 5 = 25 cm.

The area of the iron sheet is: 25 20 = 500 square centimeters.

The subtracted square side length is 5 cm.

The height of the tank is 5 cm.

The width of the original iron sheet is 20 cm.

The bottom surface of the tank is 10 cm wide.

Volume = height * width of the bottom surface * length of the bottom surface.

Bottom length = volume (height * bottom width) = 15 cm.

The original iron sheet is 25 cm long.

The area of the original iron sheet = 25 * 20 = 500 square centimeters.

The area of the iron sheet used = the original iron sheet - the 4 squares minus = 500-5 * 5 * 4 = 400 square centimeters.

Let the length of the iron sheet be x

From the question, we can get x (20-2 5), width 5, height = 750x = 15

s= (15+2×5)×20－4×5×5=400

One: 200 3 4 = 150 Peach Tree 200 4 5 = 160 Apple Tree Two: 20 125 = 16

Three: 3 7 = 3 7

5, slightly 6, the same as 3

7. (1) 2 = 120 points 40 120 = 1 3 (is the score line).

Oh, I'm a teacher, a 6th grade teacher, if you have any doubts, add me All I can tell you now is that what they said is not right at all.

I teach Chinese and have taken mathematics.

If you have any questions, just comment on it

I can't help it! That's all there is to it.

1.Peach Tree: 200 times three-quarters equals 150 Apple Tree: 200 times four-fifths equals 160

Subtract 20 times 25% or 20 times (150,000.)

Question 2: Set last year's x million yuan (1+25%)x=20 x=16

1 40 2 = 20cm < 80l can 2 5024 314 = 16cm height is 16cm3 5*8* grams.

4 6 2 = 3cm can be loaded.

6 8 2 = 4m Pond deep rice, this is the most basic in the sixth grade.

I forgot、

Hehe、Do your own homework、

1. The land area is multiplied by the height, 1 cubic decimeter = 1 liter, v = (d 2) h h = 60 cm d = 40 cm This bucket can be filled with liters, not 80 liters.

cm v= h r=10 cm, v=5024 cubic centimeters, h=16 cm.

8 grams. 4. v= (d 2) h h=10 d=6 = v=cubic centimeter, that is, it can be loaded in milliliters.

5. The volume of rice v= h r=2 h= v= cubic meter can be loaded with kilograms, that is, tons.

6. v = (d 2) h v = cubic meter d = 8 m = h = m water depth m.

6. Two methods:

Unary Equation:

Solution: The Shanghai-Hangzhou high-speed railway is about x kilometers long.

According to the title: 3 5x-17=x 2

6x-170=5x

x=170A: The Shanghai-Hangzhou high-speed railway is about 170 kilometers long.

If you haven't learned unary equations yet, use the following equation:

17x10170 (km).

A: The Shanghai-Hangzhou high-speed railway is about 170 kilometers long.

7. (The following calculations are taken.)

Solution: According to the question, the ratio is 1:50, then the water required for 20ml of concentrated juice is:

20x50=1000（ml）

Then the concentrated juice and the required amount of water are: 20 + 1000 = 1020 (ml) cylindrical cup volume: x(6 2) x15

Pour the juice into the cup 2 3, at this time the volume of juice in the cup:

If Li Mei and 3 guests want one glass each, the total juice volume:

In fact, there is only 1020ml of juice, so a glass of juice per person is not enough for Li Mei and the guests!

I don't understand how it feels like the function in school.
