Explanation:
We are asked to find what percent one number is of another. The formula is:
\[
\text{Percent} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100
\]
Then round the result to the nearest hundredth (i.e., two decimal places).
Let’s solve each problem step by step, carefully computing and rounding.

\[
\frac{31}{48} \times 100 = 64.583333... \approx 64.58\%
\]
16) 48 is what percent of 78?
\[
\frac{48}{78} \times 100 = 61.538461... \approx 61.54\%
\]
17) 27 is what percent of 48?
\[
\frac{27}{48} \times 100 = 56.25 \quad \text{(exact)} \Rightarrow 56.25\%
\]
18) 32 is what percent of 77?
\[
\frac{32}{77} \times 100 = 41.558441... \approx 41.56\%
\]

\[
\frac{19}{55} \times 100 = 34.545454... \approx 34.55\%
\]
20) 32 is what percent of 76?
\[
\frac{32}{76} \times 100 = 42.105263... \approx 42.11\%
\]
Double-checking a few for accuracy:
- #17: 27 ÷ 48 = 0.5625 → ×100 = 56.25 ✔️
- #1: 25 ÷ 29 ≈ 0.862069 → ×100 = 86.2069 → rounds to 86.21 ✔️
- #11: 36 ÷ 47 ≈ 0.765957 → ×100 = 76.5957 → rounds to 76.60 ✔️
All values are correctly rounded to the nearest hundredth.
