Let's assume

total number of pieces in a cake is x

Gabe eats another fourth of the whole cake

so,

Gabe eats

[tex]=\frac{1}{4} x[/tex]

cedric eats 3 pieces

so,

Cedric and Gade together eat

[tex]=\frac{1}{4} x+3[/tex]

we are given

Cedric and Gabe eat 9 pieces cake together

so, we can set them equal

and we get

[tex]\frac{1}{4} x+3 =9[/tex]

now, we can solve for x

Subtract both sides 3

[tex]\frac{1}{4} x+3-3 =9-3[/tex]

[tex]\frac{1}{4} x =6[/tex]

Multiply both sides by 4

[tex]\frac{1}{4} x*4 =6*4[/tex]

[tex] x =24[/tex]

so,

total number of pieces are 24.........Answer
