1. Olympiad questions.

1. Solution: There are apples in frame A and x apples in box B.

x=130130).

Answer: There are now 156 apples in the armor frame.

2. (88-3) (2+3)=17 17 3+3=54 (pages) Answer: If the first three pages of the book are illustrated, then there are 54 pages of illustrations.

The following is the language, because I am not good at the language. I won't talk about it!

1. Solution: If the total engineering quantity is "1", then A should do 1 15 every day, and B should do 1 20 every day, so when A and B cooperate, 1 15 + 1 20 = 7 60 should be done every day, and because the total engineering quantity is "1", so A and B should cooperate 1 divided by 7 60 equals 60 7 days 2, solution: or let the total engineering quantity be "1", then A does 1 15 every day, and 1 5 is done in three days, so the remaining engineering quantity is 1-1 5 = 4 5

C should do 1 25 per day, then the remaining 4 5 engineering quantity C should do 4 5 divided by 1 25 equals 16 days.

3. Solution: In the same way, A does 1 15 every day, B does 1 20 every day, and C does 1 25 every day, so A, B and C should do 1 15 + 1 20 + 1 25 = 47 300 every day when they cooperate, then A, B and C should cooperate 4 5 divided by 47 300 equals 240 47 days.

1 (1 15 + 1 20) = 60 7 days ......The number of days required for A and B to complete together (1-1 15 3) 1 25 = 20 days.

A does 3 days and C does it again, and it takes days.

3.: 4 5 (1 15 + 1 20 + 1 25) = 240 47 days. ......

A, B, and C work together, and it takes 4 5 days to complete this work.

A and B cooperation, the completion of the project needs: 1 (1 15 + 1 20) = 60 7 days Answer: A and B cooperation 60 7 days to complete.

2.A can complete 3 15 = 1 5 of the total amount for 3 days alone, and then there is still 1-1 5 = 4 5 of the total amount left

The rest of the remaining needs to be completed by B: 4 5 (1 20) = 16 days Answer: C needs 16 days to complete.

3.A, B, and C work together to complete 4 5:

: 4 5 (1 15 + 1 20 + 1 25) = 240 47 days. ......

1. It takes 60 7 for A and B to complete together, about 9 days;

2. It takes three days for A to do first, and then 20 days for C;

3. A, B, and C do it together, 240 47 (about 6 days) to complete the work 4 5 This question is very awkward, and all of them cannot be removed, the first question, the third question.

The 0 at the end of a number is multiplied by 2 and the big 5 of the hand, and 2 from 1 to 2000 is more, mainly depending on how many virtual potato liquid 5 (multiples of 5) there are from 1 to 2000:

There is a factor difference of 5:

2000 5=400, e.g. etc.

There are two factors of 5:

2000 25=80, e.g. etc., but because it has already been calculated once, it can only be added by 40 instead of 80

There are three factors of 5:

2000 125 = 16, e.g. etc., again, it has been calculated twice before, and only 8 can be added here instead of 24

There are four factors of 5:

2000 625 = 3, only 625 in 1000 is multiplied by 4 5s, because it has been used 3 times before, only 1 can be added here

The final result: the number from 1 to 2000 contains the factor 5, and the number is 400 + 80 + 16 + 3 to get 499

The circumference of the square is 20cm, and the length of the side is 5cm

The bottom edge is 5cm of the leather bridge

The height of the triangle is 5cm, and the area of the triangle is (5*5) 2=

The length of the bottom edge of the triangle is 20 4 = 5, and the height is the same as the square, which is also 5, then the area = 5 * 5 2 =

If the circumference of the square is 20cm, the side length is 5cn

The area of the triangle is 5*5 2=

The circumference of the trousers is known.

Gen Hu Jinghui manuscript according to the formula.

The square side length is 4

Sky. It's so hard at 5 years old. Crying to death.

<> A: The maximum side length of the square tile is 72 cm, and 20 tiles are needed to lay this bedroom.

The maximum common factor of 360 and 288 is 72, so the side length of the square tile is 72 cm, 360 * 288 = 103680 (square cm).

72*72=5184 (square centimeters), 103680 divided by 5184=20 (blocks).

The maximum side length is 6 cm, and there are 2880 pieces in total.

The bottom side of the box is at least 84 cm long.

①1080 4700

There is no high, choose 2 of the 3 numbers, and multiply the smallest side length 48 12 = 4 Area 4 * 4 * 6 = 96 Volume 4 3 = 64

Judgment is right.
