A is 20 yuan, B is 20 yuan, and C is 25 yuan, what is the proportion of each?

A total of 20 + 20 + 25 = 65 yuan, then the percentage of A is: 20 65, B and A are the same, the proportion is, and the percentage of C is: 25 65. Hope.

A is 20 dollars, B is 20 dollars, C is 25 dollars, A is 4/13, B is 4/13, and C is 5/13.

Step 1: First calculate the total amount of money from A, B, and C: the total amount of money from A, B, and C = 20 + 20 + 25 = 65 yuan.

Step 2: Calculate the proportion of A: A 20 65 = 4 13 Step 3: Calculate the proportion of B: B 20 65 = 4 13 Step 4: Calculate the proportion of C: B 25 65 = 5 13

So a and b each account for 4 13;c Proportion 5 13

A, B, and C contribute a total of = 20 + 20 + 25 = 65 yuan, A accounts for 20 65 = 4 13, B accounts for 20 65 = 4 13, C accounts for 25 65 = 5 13.

20 65 = 20 block proportions.

25 65 = 25 block proportions.

A proportion C proportion.

A is 20 yuan, B is 20 yuan, and C is 25 yuan, what is the proportion of each?

A accounts for 20 65 = 4 13, B accounts for 20 65 = 4 13, and C accounts for 25 65 = 5 13

A paid 28 yuan, B paid 12 yuan, a total of 40 yuan, A accounted for 28 40 =, B accounted for 12 40 =, I hope it will help you.

A paid 28 yuan, B paid 12 yuan, a total of 40 yuan, and the ratio of A and B is 70% for A and 30% for B.

The ratio of A is 28 to 40.

28:40 equals 7:10. The proportion is 70 per cent.

Your ratio is 12 to 40.

12:40 equals 3:10, and the ratio is 30%.

Answer: The three of them spent a total of 32 yuan 32 3 11 yuan to buy things.

A should give B11 yuan, C should also give 11 yuan, the remaining 10 yuan B out, and the remaining 15 yuan back to B is AA completed.

=1,5,,2,,2,,2,2,yuan.

Multivariate Stupid Omen Oak,2,,0,Yuan with side guess,0,

First calculate how much the hall forest brigade spends in total 290 + 18 = 308 If you are in the AA system, 308 divided by 4 = 77 yuan for a person to dress up as a stool is 77 yuan Because the Spring Rebellion is b, it has been 18, so 77-18 = 59, then B gives A59 yuan, and C D gives A77 yuan.

AB two people out of the sedan chair or 308 yuan, if evenly divided, 308 4 = 77, sail hall then D C should give A 77 yuan Zhaowu, B should give 77-18 = 59 yuan.

The two brothers saved a total of 200 yuan, such as Qi Heguo's brother took out 20 yuan, and the younger brother saved 25 of his own deposit, at this time the two deposits were equal, the original brother saved 120 yuan, and the younger brother saved 80 yuan.

According to the title, the original brother is x yuan.

Column equation: 200-x) 1+25%) = x-20 solution: x=120

So it turned out that the brother saved 120 yuan, and the younger brother saved 80 yuan.

Significance of solving equations:

Solving equations eliminates the difficulty of reverse thinking, and can directly list the equations containing the quantities to be solved. Equations have a variety of forms, such as unary linear equations, binary linear equations, unary quadratic equations, etc., and can also form a system of equations to solve multiple unknowns.

In mathematics, an equation is a statement of an equation that contains one or more variables. Solving the equation involves determining which values of the variable make the equation true. Variables are also known as unknowns, and the value of the unknowns that satisfies equality is called the solution of the equation.

Set a to bx after the digging.

2（30-x）=30+x

60-2x =30+x

60-30 =x+2x

3x = 30 Answer: After A gives 15 yuan to B, B is 2 times the filial piety liquid of A.

x =15

There are a total of 180 yuan, A, B, and C are the same, D is 20 yuan less than C, and A, B, C, and D are 50 yuan, 50 yuan, 50 yuan, and 30 yuan respectively.

(180+20) 4=50 (yuan).

50-20=30 (yuan).

A: A, B, and C all have 50 yuan, and D has 30 yuan.

This question can be thought of like this, if there is an additional 20 yuan ABCD, it will be the same, and (180+20) 4=50That is, ABC three is 50 yuan. Then d is 30 yuan, I hope my answer can help you.

A, B, C have the money:

(180+20) 4=50 (yuan).

d has the money is:

50-20=30 (yuan).

A: A, B, and C each have $50, and D has $30.

Because D is $20 less than C, add $20 to the total, then everyone is the same, and it can be listed as:

So, A, B, and C are all $50, and D is $30.

（180+20）/4=50

So ABC has 50 yuan for three people and 20 yuan for D.
