The number a is 4/5 of the number b. What part of that number a is number b?

Answer 1

Since a is 4/5 of be , we can write this equation:

a = 4/5 b

If you solve this equation for b by multiplying both sides of the equation by the reciprocal of 4/5 (which is 5/4), then:

5/4 a = 5/4 *4/5 b

and 5/4 a = b

Therefore a multiplied by 1.25 would give you b. The number b is 1.25 bigger than the number a
