1.Originally, there was, but now I don't know.

2.As for this question, it should be the boy who knows better, because we don't know what the boy is thinking.

3.Probably not, I think he feels sorry for that girl.

4.Maybe the boys have changed because of something.

5.The relationship is maintained by two people, if the boy has no intention, then the girl should be decisive, and the long pain is better than the short pain.

I think girls really love boys, I don't know why boys are like that! Are girls sorry for you?! There are a lot of mistakes in boys, and now it seems that the girls are completely hurt! Boys think weirdly! I was speechless.

Question 2: 5-1:8=8-1:x

x=14 Question 2: 8+7+5=20

80*8/20 = 32, 50-32 = 18

80*7/20 = 28, 30-28 = 2

A 1500 * 18/20 = 1350

B 1500 * 2/20 = 150

2.The fifth section of the saw is sawed 4 times, and the 8th section of the saw is sawed 7 times, and it takes x minutes to set it, and the ratio relationship can be obtained 4:12=7:x

x=21 means 21 minutes for sawing 8 sections.

3.From the meaning of the title.

According to the proportion, the ratio of road length to 1 represents how many people 8 + 7 + 5 = 20 50 + 30 = 80 80 20 = 4, that is, village C should produce 4x5 = 20 people, village A should produce 8x4 = 32 people, village A has 18 more people, and village B has 2 more people.

The money shared by the village is 1500x18 20 = 1350 yuan, and village B should get 1500x2 20 = 150 yuan.

Question 2: (5-1) 12=(8-1) x x=7x12 4=21A: 21 minutes.

Question 3: According to the workload of village C, the sharing ratio of villages A and B is 8:7, which has nothing to do with the number of people. A is 800 yuan, B is 700 yuan.

2.21 min. 12:4=x:7 x=21

3.1,350 yuan for village A and 150 yuan for village B (in fact, 32 people should be sent from village A, 28 people should be sent from village B, and 20 people should be sent from village C).

The second question, sawing into 5 sections, is 4 plays, so, the time of one is 12 4 = 3 minutes, sawing into 8 sections, you need to play 7 times, so the time of sawing into 8 sections is 3 7 = 21

The third question, because the labor force is dispatched according to the length, therefore, A should send 8 people, B 7 people, C 5 people, now the three villages have sent a total of 80 people, then a length should have, 80 (8 + 7 + 5) = 4 people, therefore, village A should send 4 8 = 32 people, village B should send 4 7 = 28 people, more people are sent for C, therefore, 1500 yuan from village C should be distributed to the remaining 20 people, 18 of these 20 people are from village A and 2 are from village B, so there is 1350 yuan for village A, 150 yuan to village B.

2.Let it take x minutes x:8=12:5 x=(12x8) 5=3People from Village A: People from Village B = 50:30 = 5:3

The money of the village = 1500x (5 8) =

The money shared by the village = 1500x(3 8)=

Two monomials are of the same kind, so the same letter is the same number of times.

The number of times a is the same, so 2x-2=1 x=3/2b, the number of times is the same, so 2=y-3 y=5 The data is not clear, I don't know if there is a mistake in writing, the idea is like this, I hope it will help you.
