Answer 1

Step : Expressing the given statement in
the form of percentage
Given, $21$ eggs out of $30$.
It can be written as $\frac{21}{30}$.
And $\frac{21}{30}=\frac{21÷3}{30÷3}$
$=\frac{7}{10}$
$=\frac{7\times 10}{10\times 10}$
$=\frac{70}{100}=70\%$
$\therefore 70\%$ eggs are good.
Hence, $21$ eggs out of $30$ are good in percentage
form is written as $70\%$.
