Fractions
We want to know how many cups of pecans she use to decorate one pie. Since she uses 3 cups for 12 pies, if we divide 3 by 12 we will obtain the answer:
[tex]\frac{3}{12}[/tex]
We want to simplify the fraction. Since
3 ÷ 3 = 1
12 ÷ 3 = 4
we can simplify it dividing both parts of the fraction by 3:
[tex]\frac{3}{12}=\frac{3\div3}{12\div3}=\frac{1}{4}[/tex]
Answer: D 1/4
