Question

18% of 90 is what number

Answer 1

What this means is that!
In 100 it is 18 parts!
Then in 90 it is how many parts?
So we find 18/100 of 90
Like this..... 18 * 90/100 = 16.2
Got it? :)

Answer 2

\[\frac{ 18 }{ 100 } \times 90 = \frac{ 18 \times 90 }{ 100 } = \frac{ 18 \times 9 }{ 10 }\]

Answer 3

\[ = \frac{ 172 }{ 10 } = 17.2\]
