<h3 /><h3>What is percentage?</h3>

Percentage, which may also be referred to as percent, is a fraction of a number out of 100%. Percentage means "per 100" and denotes a piece of a total amount.

To calculate the percentage , Use the percentage formula:

$X * \frac{Percentage}{100} = Y$

According to the question:

Sarah scored on the spelling test = $\frac{8}{10}$

Jonathan scored = 75%

By formulating both the values;

$\frac{8}{10} * \frac{75}{100}$

= $\frac{3}{5}$

Therefore , $\frac{3}{5}$ is the score of Jonathan.
