Question

54 is 72% of what number?

Answer 1

Using Y as the answer, 54/72% = Y/100%. 72Y = 54 x 100, 72Y = 5400 divided by 100 = 75.

Answer 2

54 is 72% of 75.

This problem requires simple division in which we will be dividing 54 by 0.72:

54 / 0.72 = 75

This can be checked through calculation of 72% of 75, which can be started with by dividing 75 by 10 to find 10% of 75:

75 / 10 = 7.5, and we can divide again by 10 to find that 0.75 is 1% of 75.

Now that we have 1%, we multiply it by 72 to find that:

0.75 • 72% = 54

Therefore, 54 is 72% of 75.
