Answer:
B. 7 1/2 cups
Explanation:
Zoe uses 1 1/4 cups of flour in each batch of cookies. So, first, let's convert 1 1/4 to a fraction as follows
[tex]1\frac{1}{4}=\frac{(1\times4)+1}{4}=\frac{4+1}{4}=\frac{5}{4}[/tex]
It means that Zoe uses 5/4 cups of flour in each batch. Then, the amount used in 6 batches will be 6 times 5/4 cups which is equal to
[tex]6\times\frac{5}{4}=\frac{6\times5}{4}=\frac{30}{4}=\frac{15}{2}[/tex]
Now, we need to convert 15/2 into a mixed number.
Dividing 15 by 2, we get a quotient of 7 and a remainder of 1, so
[tex]\begin{gathered} \frac{15}{2}=Quotient\frac{\text{Remainder}}{\text{Divisor}} \\ \frac{15}{2}=7\frac{1}{2} \end{gathered}[/tex]
So, the answer is
B. 7 1/2 cups
