25%

Explanation:

For calculating a number x as a percentage of another number y, one has to calculate (x xx100)/y%.

As such, 18 as a percentage of 72 will be (18xx100)/72%=(1cancel(18)xx100)/(4cancel(72)

= 100/4=(25cancel(100))/(1cancel(4))=25%

For me, I usually change it to fraction in simplest form first.
18-:72 = 0.25

0.25 = 25%

Okay, I do admit it doesn't work most of the time.

A = 25%

Explanation:

First, let's divide 72 / 18

= 4

Thus, we know that 18 goes into 72 4 times, and that means that 18 is 1/4 of 72. Now, we just have to convert 1/4 into a percent. The way we find the percentage is by converting this fraction into a decimal:

= 1/4
= 0.25

We can now find the percentage by simply looking at the decimal.
And thus, the answer is 25%

All the best!
