Question

Mindy and Troy combined ate 9 99 pieces of the wedding cake. Mindy ate 3 33 pieces of cake and Troy had 1 4 4 1 ​ start fraction, 1, divided by, 4, end fraction of the total cake.

Answer 1

(a)There are 24 cakes in total

(b)There are 15 pieces of cakes left

Explanation:

Let the total cakes=x

Let number of cakes eaten by Mindy=m

Let number of cakes eaten by Troy=t

Now:

m=3

Since m+t=9

3+t=9

t=9-3=6

The Number of Pieces of Cake Left in Total=x-(t+m)

Since Troy had
`(1)/(4)` of the total cake

`(1)/(4) of x=6`

`(1)/(4) X x=6`

x=6X4=24

(a)There are 24 cakes in total

(b)The Number of Pieces of Cake Left in Total=x-(t+m)=24-9=15 cakes
