Practice the questions of McGraw Hill Math Grade 4 Answer Key PDF Chapter 8 Lesson 5 Adding Mixed Numbers to secure good marks & knowledge in the exams.

Question 1. 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. 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. 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. 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?
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$$\frac{3}{5}$$
$$\frac{4}{5}$$ + $$\frac{1}{5}$$ + $$\frac{3}{5}$$ = $$\frac{8}{5}$$ = 1$$\frac{3}{5}$$
4 + 8 + 6 + 1$$\frac{3}{5}$$ = 19$$\frac{3}{5}$$ hours
