Question

a is 7 time of a b. b is how much percent less than A​

Answer 1

Answer:

A= 7B and so B/A = 1/7

(A-B)/A=A/A-B/A=1-1/7=7/7-1/7=6/7

Step-by-step explanation:

So B is less than a by5 parts out of 7. when multiplied by 100,B is less than A by(83 1/3)%

Answer 2

Answer: A is 7 times more than B.

So if B = 1, A= 1 + (1 x 7) = 8

What is being compared = how much B is less than A = 8 - 1 = 7

To whom it is compared = It is compared with A = 8

=> Percent = 7/8 x 100 = 87.5/8 %
