# How do you express 7.5 cupcakes in dozens?

Aug 13, 2016

$7.5$ cupcakes are $\frac{5}{8}$ dozens of cupcakes

#### Explanation:

As in one dozen we have $12$ items, to convert a given number of items into dozen, we need to divide that number by $12$.

Hence, $7.5$ cupcakes are equivalent to $\frac{7.5}{12}$ dozen cupcakes.

7.5/12=75/(10×12)

= (cancel(75)^25)/((2×5)×(cancel12)^4)

= (5×cancel(5))/(2×cancel(5)×4)

= $\frac{5}{8}$

Hence $7.5$ cupcakes are $\frac{5}{8}$ dozens of cupcakes.
