Answer 2

Answer:

The 30% of the number is 18.

Step-by-step explanation:

Given 90% of a number is 54.

Percentage is a number that is expressed as a decimal fraction, with the denominator 100.

Percent means per hundred.

To calculate the percentage of a number, i.e., x% of number n is given by

$\dfrac{x}{100}\times n$

Let the number be $x$.

90% of $x$ is equal to 54.

$\dfrac{90}{100}\times x= 54$

$\implies \dfrac{9}{10}\times x= 54\implies 9 x= 54\times 10$

$\implies x=\dfrac{54\times 10}{9} \implies x=6\times 10=60$

30% of the number is 30% of 60

$\dfrac{30}{100}\times 60= 3\times 6=18$

Therefore, the 30% of the number is 18.
