b. \( \frac{8}{4+5}+5 \)

Let's break this down! First, you’ll want to solve the fraction: \( \frac{8}{4+5} \). Here, \( 4 + 5 \) equals \( 9 \), so the fraction simplifies to \( \frac{8}{9} \). Now, add \( 5 \) to that fraction. It helps to express \( 5 \) as \( \frac{45}{9} \) (so they have a common denominator). Now you can add: \[ \frac{8}{9} + \frac{45}{9} = \frac{53}{9} \] So, the final answer in improper fraction form is \( \frac{53}{9} \) or \( 5 \frac{8}{9} \) if you want a mixed number!
