**Add**

**Write your answers in simplest form.**

Question 1.

Answer:

The Denominators of the given fractions are the same so add the numerators.

\(\frac{1}{2}\) + \(\frac{1}{2}\) = 1

1 + 4 + 1 = 6

Question 2.

Answer:

The Denominators of the given fractions are the same so add the numerators.

\(\frac{1}{3}\) + \(\frac{1}{3}\) = \(\frac{2}{3}\)

4 + 3 + \(\frac{2}{3}\) = 7\(\frac{2}{3}\)

Question 3.

Answer:

The Denominators of the given fractions are the same so add the numerators.

\(\frac{2}{7}\) + \(\frac{4}{7}\) = \(\frac{6}{7}\)

16 + 9 + \(\frac{6}{7}\) = 25\(\frac{6}{7}\)

Question 4.

Answer:

The Denominators of the given fractions are the same so add the numerators.

\(\frac{3}{5}\) + \(\frac{1}{5}\) = \(\frac{4}{5}\)

24 + 7 + \(\frac{4}{5}\) = 31\(\frac{4}{5}\)

Question 5.

Last month Mr. Garrett flew three times. The first flight lasted 4\(\frac{4}{5}\) hours and the second flight lasted 8\(\frac{1}{5}\) hours. The third flight lasted 6\(\frac{3}{5}\) hours. For how many hours did Mr. Garrett travel?

Answer:

Given,

Last month Mr. Garrett flew three times.

The first flight lasted 4\(\frac{4}{5}\) hours and the second flight lasted 8\(\frac{1}{5}\) hours.

The third flight lasted 6\(\frac{3}{5}\) hours.

4\(\frac{4}{5}\) + 8\(\frac{1}{5}\) + 6\(\frac{3}{5}\)

The Denominators of the given fractions are the same so add the numerators.

\(\frac{4}{5}\) + \(\frac{1}{5}\) + \(\frac{3}{5}\) = \(\frac{8}{5}\) = 1\(\frac{3}{5}\)

4 + 8 + 6 + 1\(\frac{3}{5}\) = 19\(\frac{3}{5}\) hours
