To find out what percentage 35 is of 80, you can use the formula:
\[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 \]
In this case, the "Part" is 35, and the "Whole" is 80. Plugging in the numbers:
\[ \text{Percentage} = \left( \frac{35}{80} \right) \times 100 \]
Now, calculate \( \frac{35}{80} \):
\[ \frac{35}{80} = 0.4375 \]
Now, multiply by 100 to convert to percentage:
\[ 0.4375 \times 100 = 43.75 \]
Thus, 35 is 43.75% of 80. Rounding to the nearest hundredth gives 43.75%.
The answer is:
\(\text{43.75%}\)
