Answer:  Marry drank less than half of her glass of juice.

Step-by-step explanation:  Given that Larry, Mary and Terry each had a full glass of juice.Larry drank $\dfrac{3}{4}$ of his. Mary drank $\dfrac{3}{8}$ of hers and Terry drank $\dfrac{7}{10}$ of his.

We are to find who drank less than $\dfrac{1}{2}$ of their juice.

We have

Portion of the glass of juice that Larry drank

$=\dfrac{3}{4}>\dfrac{2}{4}\left(=\dfrac{1}{2}\right).$

Portion of the glass of juice that Mary drank

$=\dfrac{3}{8}$
