Question

What is the value of 40% of 60?

Answer 1

Hint: We are asked to find a certain percentage of some number. Therefore, we should express the percentage as a ratio and then multiply it with the given number to find the answer to the question.

Complete step-by-step answer:
We should learn how to express a percentage in the form of a ratio. We can express the expression for x percentage of a quantity Q as
$\text{x percentage of Q=}{\displaystyle \frac{x}{100}}\times \text{Q}................\text{(1}\text{.1)}$
In this question we have to find 40% of 60. Therefore, we should take x=40 and Q=60 in equation (1.1). Therefore, we can write the expression as
$\text{40 percent of 60=}{\displaystyle \frac{40}{100}}\times 60=24$
Therefore, we obtain that 40 percent of 60 is 24 which has been asked in the question. Therefore, the answer should be equal to 24.

Note: We should be careful that the answer obtained after taking the percentage should not contain a percentage sign because it expresses the fraction of the number which corresponds to the taken percentage. Also, we should note that in mathematical expressions, we can use the trick that in calculations, the % symbol should be replaced by ${\displaystyle \frac{1}{100}}$ to give the required answer. For example, in this question, 40 percent corresponded to $40\times {\displaystyle \frac{1}{100}}$ and was replaced with the $\times$ to give the correct answer.
