Answer:
[tex]6\ cups[/tex]
Step-by-step explanation:
Problem
To make a cake, I need a cup and a half of sugar. How many cups of sugar will I need to make [tex]4[/tex] cakes?
we know that
To make [tex]1[/tex] cake is needed [tex]1\frac{1}{2}[/tex] cups of sugar
so
To find how sugar is needed multiply [tex]1\frac{1}{2}[/tex] by [tex]4[/tex]
Convert mixed number to an improper fraction first
[tex]1\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}[/tex]
[tex]4*\frac{3}{2}=6\ cups[/tex]
