Allison can make 4 fruit parfaits.
Since one parfait requires 1/8 cup of yogurt, add:
1/8 + 1/8 + 1/8 + 1/8
They all share a common denominator, so:
1/8 + 1/8 +1/8 + 1/8 = 4/8
Simplify your answer (divide numerator and denominator by the common factor of 2) :
4/8 = 1/2
1/2 represents the total amount of cups of yogurt used. Since it took adding 1/8 four times that represents 4 parfaits.
