Answer:
8 times
Step-by-step explanation:
Naomi has [tex]\frac{1}{4}[/tex] cup but she needs 2 whole cups.
So how many [tex]\frac{1}{4}[/tex] are there in 2???
We can divide 2 by [tex]\frac{1}{4}[/tex] to get the number of "one-fourths" there is in 2.
[tex]\frac{2}{\frac{1}{4}}\\=2*\frac{4}{1}\\=2*4\\=8[/tex]
