Question

how many quarters are in $5?

Explanation:

Identify the value of a quarter

$$ 1\text{ quarter} = \$0.25 = \frac{1}{4}\text{ dollar} $$

Calculate the number of quarters in one dollar

$$ \text{Quarters per dollar} = \frac{\$1.00}{\$0.25} = 4 $$

Multiply by the total dollar amount

$$ \text{Total quarters} = 5 \times 4 = 20 $$

20
