The ratio of a to B is 4 to 7. How many points is a less than B and how many points is B more than a?

The number of a is 3 / 7 less than that of B, and the number of B is 3 / 4 more than that of A
Formula: A is x, B is y
x/y=4/7
x-y/y=x/y-1=-3/7
Similarly, Y-X / x = 3 / 4

The number of a is 8 times more than that of B. the total number of a is 952, which is 5 times more than that of B. what is the number of a? What's the number B?

(8 × 7 + 952) △ 7 + 5, = (56 + 952) △ 12, = 1008 △ 12, = 84; 84-8 = 76; answer: number a is 84, number B is 76

The number of a is 8 times more than that of B. the number of a is 5 times more than that of B. the total number is 952. What are the numbers of a and B

Let B be X
The number of a is x + 8
The equation 5 * (x + 8) + 7 * x = 952 can be obtained
The solution is x = 76
The number of a is 76 + 8 = 84
The number of B is 76
