Question

Mindy and Troy combined ate 9 pieces of a wedding cake.

Mindy ate 3 pieces and troy ate 1/4 pieces.
Write an EQUATION to determine how many pieces of cake were there in total.
how many pieces were there in total?

Answer 1

Let x be the total number of pieces of cake.

Mindy ate 3 pieces,

troy ate x/4

Between them 2 they ate 9 pieces

we write the equation 3+x/4=9

we solve:

x/4 = 9-3

x/4 = 6

x/4 = 24/4

x= 24

there were 24 pieces of cake
