the number a is smaller than the number b by 1/5 of b . by what part of a is b bigger than a?

Bigger by ¼ of a.

Step-by-step explanation:

Let b be represented by all five slices of the pie, and a by the four yellow slices.

Then a is ⅘ of the pie and it is ⅕ smaller than b.

Now, let's turn the argument around.

The four yellow slices represent a, and all 5 slices represent b.

b is greater than a by one slice compared to four.

In mathematical terms, b is bigger by ¼ of a.

b
