$7.5$ cupcakes are $5/8$ dozens of cupcakes

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 $7.5/12$ dozen cupcakes.

$7.5/12=75/(10×12)$

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

= $(5×cancel(5))/(2×cancel(5)×4)$

= $5/8$

Hence $7.5$ cupcakes are $5/8$ dozens of cupcakes.
