Question

Jessica has 4/8 of a bottle of Robitussin syrup on hand. The pharmacist instructs Jessica to reduce the syrup by 1/2 so he can prepare a patient’s prescription. How much Robitussin does the pharmacist need to prepare the prescription?

Answer 1

0

Explanation:

First, in order to subtract these fractions, we need the denominators to be the same number.

4/8 x 2 = 8/16

1/2 x 8 = 8/16

8/16 - 8/16 = 0. The doctor does not need any Robitussin at all
