How much is 1 4 cup plus 1 4 cup

Answer:

Juan’s expression is not correct because 1 3/8 equals 11/8 and John used 12/8

$5frac{1}{2} cup servings$

Step-by-step explanation:

we know that

To find out how many 1/4 cup servings are in 1 3/8 cups of juice, divide 1 3/8 cups of juice by 1/4 cup servings

$1frac{3}{8}:frac{1}{4}$

but first

Convert mixed number to an improper fraction

$1frac{3}{8}=1+frac{3}{8}=frac{1*8+3}{8}=frac{11}{8}$

substitute in the expression above

$frac{11}{8}:frac{1}{4}=frac{11}{2}$

Convert to mixed number

$frac{11}{2}=frac{10}{2}+frac{1}{2}=5frac{1}{2} cup servings$

Juan’s expression is not correct because 1 3/8 equals 11/8 and John used 12/8
