1, A 110, B 160 x + y = 260 x - 14 =

2,x=1 4(x+y+z) z=2y z=x+90 x=90 y=90 z=90 270 in total.

3. A 1080 yuan, B 270 yuan.

If A is two-thirds more than B, it can be said that the ratio of A to B is 5:3;The ratio of A to B is 5:4; A remains the same, B 4-3 = 1, and 1 part is just 9 people.

That is, 4 times 9 = 36, 36-9 = 27Now there are 27 people left.

Then the number of students in class A is two-thirds of the number of students in class B

That's right???

(1) 121 (2) He read 90*1 15=6 pages on the first day, 90*1 10=9 pages on the second day, and a total of 9+6=15 pages in two days. So on the third day he should start on page 16.

3) The first use is (16 15) * (1 4) = 4 15 m The second use is (16 15-4 15) * (1 4) = 3 15 m.

So two times shared go 4 15 + 3 15 = 7 15 meters.

4) 24*1 3*1 2=4.

5) 125*4 5*4 5*4 5=64m.

6) Barrel A: 4 (1 5) = 20 kg Barrel B: 20-4 = 16 kg.

7) 240*(1-1 6)-120=80 km.

8) Xiao Ming is more than Xiao Qiang (48 * 1 12 * 2) = 8 sheets So Xiao Qiang has 40-8 = 40 sheets.

9) Chinese: 45*3 5=27 Mathematics: 45*2 3=30 people There are 30+27-45=12 people who like both Chinese and mathematics.

10) 27 28 * (1 (1 + 8)) = 3 28 meters.

11) (1 4) (2*2*2) = 1 32 (ha).

12) (1 5) * (5 6) = 1 6 1 (1 6) = 6 hours.

13) 72*(1-(1 4)-(1 6)) = 42.

There are 40 thinking training questions in mathematics, the question type is very flexible, it is recommended that parents can print a copy for their children, and students who are not serious are easy to fall into it, and they will get full marks. At the end of the article, memory training methods are attached to improve children's learning efficiency.

Big Fat took the remaining half of the more than three pieces, and then there was no more This means that 3 pieces account for the remaining total 1 2 Ah, this means that Big Fat took six pieces.

Looking at Xiaopang again, it is also half of the total, and there are 3 more pieces and 6 pieces left, so a total of (3*2+3)*2=18

I don't know if I understand that.

When the big fat is not taken, there are 3 (1 2) = 6 pieces, and the remaining half is 3 pieces.

When Chubby didn't take it, there were (6+3) (1 2)=18 pieces, and half of all was 6+3 pieces.

Mom bought back 18 yuan.

Total grain: 130 + 87 + 60 = 277 (tons) When the grain in warehouse A is twice that of warehouse B, there is grain in warehouse B:

277 (1+2)=277 3 (tons).

B shipped in: 277 3-87 = 16 3 (tons).

A shipped in: 60-16 3 = 164 3 (tons).

After being brought in, if the grain in warehouse A is twice that of warehouse B, the total amount of grain is three times that of warehouse B.

Therefore, the final grain storage in warehouse B: (130+87+60) 3=277 3 tons, then warehouse A is about 2*277 3=554 3 tons.

So warehouse A shipped in 554 3-130= tons.

Warehouse B brings in 277 3-87= tons.
