Question

1. - / 1 points evaluate t + h for t = 1/2 and h = 5/9.

Explanation:

Step1: Substitute values

Substitute $t = \frac{1}{2}$ and $h=\frac{5}{9}$ into $t + h$. So we get $\frac{1}{2}+\frac{5}{9}$.

Step2: Find common denominator

The common - denominator of 2 and 9 is 18. Rewrite the fractions: $\frac{1}{2}=\frac{1\times9}{2\times9}=\frac{9}{18}$ and $\frac{5}{9}=\frac{5\times2}{9\times2}=\frac{10}{18}$.

Step3: Add fractions

$\frac{9}{18}+\frac{10}{18}=\frac{9 + 10}{18}=\frac{19}{18}$

Answer:

$\frac{19}{18}$
