Question

X Zoe uses 1 cups of flour in each batch of cookies. How much flour will she use in 6 batches? O A. 7 cups 71 O B. 7 cups 0 C. 85 cups O D, 9 cups

Answer 1

B. 7 1/2 cups

Step-by-step 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

`1(1)/(4)=((1*4)+1)/(4)=(4+1)/(4)=(5)/(4)`

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

`6*(5)/(4)=(6*5)/(4)=(30)/(4)=(15)/(2)`

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

`\begin{gathered} (15)/(2)=Quotient\frac{\text{Remainder}}{\text{Divisor}} \\ (15)/(2)=7(1)/(2) \end{gathered}`

So, the answer is

B. 7 1/2 cups
