5% of the number a is equal to 30% of the number B. the number a is a few percent of the number B, and the number B is a few more than the number a

5% of the number a is equal to 30% of the number B. the number a is a few percent of the number B, and the number B is a few more than the number a

A × (5 / 12) = B × 0.3;
A = B × 0.3 × (12 / 5) = B × 18 / 25;
The ratio of a to B is 18 / 25 × 100% = 72%;
Number B is more than number a = (1-0.72) △ 0.72 = 0.28/0.72 = 28 / 72 = 7 / 18;
If you don't understand this question, you can ask,

Given that the difference and quotient of two numbers are equal to 8, then the sum of the two numbers is ()
emergency

a-b=8
a/b=8
∴7b=8 b=8/7
a=64/7
a+b=72/7

A number whose quotient is equal to the sum of two numbers
Be accurate

a/b=a+b
a=ab+b^2
b^2+ab-a=0
a=b^2/(1-b)
Any other requirements?

The quotient and difference of a and B are all equal to 5, so we need to find these two numbers. Thank you!

A-B = 5
A / b = 5
A = 5 B
5 B - B = 5
B = 5 / 4
A = 25 / 4
