Question

Glen invited 25 people to his birthday party.

Answer 1

Answer:

20% of the invited people did not attend

Step-by-step explanation:

5 out of 25 people invited didn't attend Glen's party. That means the following:

$\frac{5}{25}$  people didn't come which simplifies to  $\frac{1}{5}$

Multiply $\frac{1}{5}$ by the giant one $\frac{20}{20}$ so the denominator is 100 which is the denominator used to find percentages.

You end up with $\frac{20}{100}$

$\frac{20}{100}$ = 20%
