Question

There are 18 cupcakes. How many 3/4 size servings can you make?

Answer 1

Since its 3/4 serving and there are 18 pancakes
18 divided by 3/4
just find the reciprocal (switch the denominator and numerator) and change divide to multiply
18 x 4/3 = 24 servings
the reason being for multiplying the reciprocal: there is a rule stating that whenever you divide something by a fraction, you change the divide sign to a multiplying sign and flip the flip the digits in the numerator and denominator section in the fraction (basically the fractions reciprocal)

or another way of doing it is
3/4 = 0.75
18/0.75 = 24
but you'll likely to need a calculator for that
