How to I find the estimate of 25% of 230

MArishka [77]

The key to understanding the question is to keep the details at the fore.

Percentage = 25%

Amount = 230

Our answer to the estimation is given by the formula:

$\begin{gathered} \text{Percentage }\cdot\text{ Amount = 25\% }\cdot\text{ 230} \\ =\frac{25}{100}\cdot230=\frac{25\cdot230}{100} \\ =57.5 \end{gathered}$
