Answer:
[tex]6 \frac{3}{8}[/tex]
Step-by-step explanation:
Let's start by turning 8 1/2 into an improper fraction, which would be 17/2. To find the amount of cups needed for a cake that is 3/4 of a full cake, we multiply 17/2 by 3/4.
[tex]\frac{17}{2} *\frac{3}{4} = \frac{17*3}{2*4} = \frac{51}{8}[/tex]
Turn the fraction into a mixed number:
[tex]6 \frac{3}{8}[/tex]
That should be the correct answer. Hope this helps!!!
