Question

What is four fifths plus eight ninths

Answer 1

4/5 + 8/9. First we have to find a common denominator for $\frac{4}{5}$ and $\frac{8}{9}$. $\\ \frac{4*9}{5*9}= \frac{36}{45} \ and \ \frac{8*5}{9*5}= \frac{40}{45}$ Now we are going to add:$\frac{36}{45}+ \frac{40}{45}= \frac{76}{45}$ Make $\frac{76}{45}$ a mixed number:$\frac{76}{45}=1 \frac{31}{45}$ So the answer is $\boxed{1 \frac{31}{45}}$
