1.Solution: 65 5 7 20% = 65 7 5 20% = 91 20% = 2Solution: Let the number B be x

60%x+10=100

x=150Answer: The number B is 150

1. Cutting according to the length of the edge is the largest. 1 3 * cubic decimeters) 2, sugar and water according to 1:4. Then the sugar water is 5 times that of sugar, 10 * (1 + 4) = 50 (g) 3, solution: if it should be transferred to person A x, then it should be transferred to B 20-x.

27+x=2*（19+20-x）

x=1720-17=3 (person).

1. The diameter and height of the bottom surface of the cone after cutting are 6 decimeters, and the radius of the bottom surface is 6 2 3 decimeters cubic decimeters.

2. Water has 10x4 40 grams of sugar water, a total of 10 + 40 50 grams of column, and the comprehensive formula is 10x4 + 10 50

3. After joining 20 people, there are a total of 27+19+20 66 people divided into 3 parts, and B accounts for 1 share, and A accounts for 2 shares 66 3 22 This is the number of people that B should have.

17 people should be transferred to Division A and 3 persons to Division B

decimeter) 3 * 3 * cubic decimeter).

Serving) 10 * 5 = 50 (grams).

3.Solution: Set up a person to be transferred into X person.

27+x=2（19+20-x）

27+x=78-2x

52=3xx=17

20-17 = 3 (people).

*3 * cubic decimeters).

10*4=50 (grams).

3. Set up x people at place B, then 27+(20-x)=(19+x)*2 solution x=3 20-3=17

Answer: There are 17 people in the first division and 3 people in the second office.

1. Cutting according to the length of the edge is the largest. 1 3 * cubic decimeters) 2, sugar and water according to 1:4. Then the sugar water is 5 times that of sugar, 10 * (1 + 4) = 50 (g) 3, solution: if it should be transferred to person A x, then it should be transferred to B 20-x.

27+x=2*(19+20-x)

x=1720-17=3 (person).

1 solution 20 5 60 5 3 = 20 kg 2 solution The original number of girls is 5x

The number of boys is 6x

5x+5﹚÷6x=8/9

48x=45x﹢45

3x=45x=15

The number of female students is 5x = 75

The number of boys is 6x=90

km h), 1 hour 30 minutes + 3 hours = 4 hours 30 minutes 4 hours 30 minutes * 60 = 270 (km).

A: A and B are 270 kilometers apart.

Minute 3This question seems to be wrong, because if the decimal point of A is moved to the right by 2 places, it will be expanded by 100 times, and it can be seen from the meaning of the question that the number B is 6x larger than the number A

Question 1: Truck speed: 180 3 = 60 kilometers per hour, 1 hour and 30 minutes is equal to hours, the hour travels kilometers, add the 180 kilometers in front to the 90 kilometers behind, and the distance between A and B is 180 + 90 = 270 (kilometers).

Sorry for that.

1. v=180 3=60 km Hours The distance between the two places s=60 km hours * (3 + hours = 270 km.)

2. Let the inlet speed of the inlet pipe be v1, the outlet speed of the outlet pipe v2, and the unit 1 after the pool is full, and the following equation can be obtained according to the title:

v2*1 6 hours = 1, solution v2 = 6, (v1-v2)* solution v1 = 10, open the water inlet pipe separately and fill the pool water with t hours, v1 * t = 1, t = hour = 6 minutes.

3. The title is wrong.

4、？5, hook 6, fork.

1.(180 3) (3+km)23 minutes 1 15 + 1 10 = 1 6 So fill the pool for 6 minutes and half for 3 minutes.

3.Question, is there a mistake? Coming out is negative.

6.In the case of a negative number) (when the number B is zero, it is equal to the same difference).

9x7x25 = 1575 cubic centimeters = 1575 ml.

4x5x10 = 200 cubic centimeters = 200 ml.

A: The first nipple bottle can hold 1575 ml of yogurt, which can be poured into 7 boxes of cuboid boxes, and there is 175 ml of yogurt left.

9*7*25=1575 (cubic centimeters).

1575 cubic centimeters = 1575 milliliters.

A: He can hold 1575 ml of yogurt.

7*5*10=350 (cubic centimeters).

350 cubic centimeters = 350 milliliters.

1575 350 = 4 (box)...175 (ml) A: You can pour 4 boxes, and there are 175 ml left.

What about the width of the box locket? The conditions are not complete!

1.Let this number be x, then:

x + x*

Thus, = , x=

2.Let the number A be x and the number B be y, then:

x+, thus, x=, i.e., the number A is 80 percent of the number B

1.Let this number be x, establish the equation x+, and solve x=

2.A*(1+1 4)=B, then A B = 4 5, A is 4 5 of B

1. x+ x=

2.A + 1 4 A = B 5 4 A = B.

A = 4 5 B = 80% B.

2A + 1 4 A = B.

5 4 A = B.

A = 4 5 B = B = 80% B.
