# Benny drank 4 over 10 liter of juice.His brother drank as much as him and 1 over 10 more,and his sister drank half as much as him.How much juice did the three children drink?

## why clutter things up with all the words? You clearly know how to write fractions.

Benny: 4/10

Brother: 4/10 + 1/10 = 5/10

Sister: (1/2)(4/10) = 2/10

Assuming "him" again refers to Benny. (And it should be "he" anyway)

Now add up the amounts.
