Express the following statement in the percentage form: ​
$21$ eggs out of $30$ are good.

Answer 1

Step 1: Expressing the given statement in the form of percentage

Given, $21\text{eggs out of}30$

It can be written as $\frac{21}{30}$

$\frac{21}{30}=\frac{21÷5}{30÷3}$

$=\frac{7}{10}$

$=\frac{7\times 10}{10\times 10}$

$=\frac{70}{100}=70\%$

$\therefore 70\%$ eggs are good.

Hence, $21\text{eggs out of}30$ are good in percentage form is written as $70\%$.
