A recipe 5

A recipe called for 1 7/8 cups of chopped onions and 2 7/8 cups of diced spinach. How many more cups of spinach did the recipe call for?

Correct answer:

x =  1

Step-by-step explanation:

$$\begin{gathered} a=1\frac{7}{8}=1+\frac{7}{8}=\frac{1\cdot 8+7}{8}=\frac{8+7}{8}=\frac{15}{8}=1\frac{7}{8}=1.875 \\ b=2\frac{7}{8}=2+\frac{7}{8}=\frac{2\cdot 8+7}{8}=\frac{16+7}{8}=\frac{23}{8}=2\frac{7}{8}=2.875 \\ x=b-a=\frac{23}{8}-\frac{15}{8}=\frac{23-15}{8}=\frac{8}{8}=1 \end{gathered}$$
