Question

Jennifer drank $\frac{5}{16}$ of a jar of juice, while Eric drank $\frac{3}{16}$ of the juice. If Lewis drank the same as Eric, how much did they drink altogether?

• A. $\frac{9}{16}$
• B. $\frac{13}{16}$
• C. $\frac{11}{16}$
• D. $\frac{8}{16}$

Answer 1

The correct option is C $\frac{11}{16}$

Jennifer drank $\frac{5}{16}$.
Eric drank $\frac{3}{16}$.
Lewis drank the same as Eric, so he also drank $\frac{3}{16}$.
Total juice drunk by all of them is
$\frac{5}{16}+\frac{3}{16}+\frac{3}{16}$
All these are like fractions. To add like fractions, we have to add the numerators only.
$\frac{5}{16}+\frac{3}{16}+\frac{3}{16}=\frac{5+3+3}{16}=\frac{11}{16}$
Hence, they drank $\frac{11}{16}$ juice altogether.
