36 is 80% of what number

If 36 is 80% (a piece) of a number. that means the number must be higher than 36

Changing the English to math:

36 = 80% x n (n being the number)

36 =.8n (changed the percent to a decimal by moving it back two places

36 =.8n

.8.8 I divided both sides by. 8 - when you divide a number by a decimal (less than one) the number will become larger.

The answer is 45
