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.
McGraw Hill Math Grade 4 Chapter 8 Lesson 5 Answer Key Adding Mixed Numbers 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 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
