D'naya has 5/6 pounds of cups of frosting to put on batch of cupcakes. He puts 1/8 of a cup on one cupcake. How much does he have left to use on the rest of the batch?

Respuesta :

5/6 - 1/8 = 5(8)/[6(8)] - 1(6)/[8(6)]
5/6 - 1/8 = [5(8) - 1(6)]/[8(6)]
5/6 - 1/8 = [40 - 6]/[48]
5/6 - 1/8 = [34]/[48]
5/6 - 1/8 = 17/24 (reducing the fraction by diving top/numerator and bottom/denominator by 2)
