#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.
