Question

1. a child was given 1/2 ml, 5/8 ml and 7/8 ml of a medication. how much in total medication in millilitres did the child receive?

Explanation:

Step1: Identify the amounts

The child was given $\frac{1}{2}$ mL and $\frac{5}{8}$ mL and $\frac{7}{8}$ mL of medication.

Step2: Find a common - denominator

The common denominator of 2 and 8 is 8. Convert $\frac{1}{2}$ to eighths: $\frac{1}{2}=\frac{1\times4}{2\times4}=\frac{4}{8}$ mL.

Step3: Add the amounts

Add $\frac{4}{8}+\frac{5}{8}+\frac{7}{8}=\frac{4 + 5+7}{8}=\frac{16}{8}=2$ mL.

Answer:

2 mL
