Question

What number is \[15\% \] of 64?

Answer 1

Hint: Percentage basically means that per 100. Or we can say divided by 100. So we will find 15% of 64. That is 64 is multiplied by the ratio of \[\dfrac{{15}}{{100}}\]. The answer so obtained will be simplified to its simplest form such that numerator and denominator has only one common multiple 1.

Complete step-by-step answer:
Given the number is 64 whose 15% is to be found.
 So, \[15\% = \dfrac{{15}}{{100}}\]
So we will multiply the given number by the ratio above,
\[ = \dfrac{{15}}{{100}} \times 64\]
On dividing the ratio by 5 we get,
\[ = \dfrac{{3 \times 64}}{{20}}\]
Now dividing by 4 we get,
\[ = \dfrac{{3 \times 16}}{5}\]
Now multiply the numbers in the numerator,
\[ = \dfrac{{48}}{5}\]
This is the only simplied form because the numerator and denominator has common multiple 1. So 15% of 64 is \[ = \dfrac{{48}}{5}\]
So, the correct answer is \[ = \dfrac{{48}}{5}\]”.

Note: Here just note that “of” operator means multiplication. This is the only thing to note. Also note that sometimes the language of the question is what percent of 64 is \[\dfrac{{48}}{5}\]. Thus this can be solved by the way below.
\[\dfrac{x}{{100}} \times 64 = \dfrac{{48}}{5}\]
Thus used the “of” operator.
