Step-by-step explanation:
If Zack has 3/4 cups of icing, and he has to put it on 6 cupcakes, that means that he has to equally divide the icing so that he can put the same amount on each cupcake.
Therefore, we need to do the keep, change, flip method. This method consists of flipping the numerator and denominator of the 2nd number in the division problem, and then multiplying the two fractions. In this problem...
3/4 divided by 6 equals 3/4 x 1/6
--> 1/8. Zack needs to put 1/8 cups of icing on each cupcake.
