Q:

Paul is making banana bread. The number of cup of bananas he uses is proportional to the number of loaves of bread. Paul uses 11 1/4 cups of bananas to make 5 loaves of bread. Which equation represent the relationship between c, the number of cups of bananas, and , the number of loaves of bread?

Accepted Solution

A:
Let
c----------> the number of cups of bananas
l----------> the number of loaves of bread

we know that
11 1/4------> (11*4+1)/4-----> 45/4

 Paul uses (45/4) cups of bananas to make------->  5 loaves of bread
then
  1 cup of banana------------------------------------> X
X=(1*5)/(45/4)--------> x=20/45--------> 4/9 loaves of bread

so 
the equation that represent the relationship between c, and l is
c=(4/9)*l

the answer is
c=(4/9)*l
