To determine what percent 40 is of 50, follow these steps:
1. First, understand the problem: We need to find the percentage of 40 out of 50.
2. The formula to find the percentage is:
[tex]\[
\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100
\][/tex]
3. In this case, the "Part" is 40 and the "Whole" is 50. Substitute these values into the formula:
[tex]\[
\text{Percentage} = \left( \frac{40}{50} \right) \times 100
\][/tex]
4. Simplify the fraction [tex]\(\frac{40}{50}\)[/tex]:
[tex]\[
\frac{40}{50} = 0.8
\][/tex]
5. Multiply 0.8 by 100 to convert it to a percentage:
[tex]\[
0.8 \times 100 = 80
\][/tex]
6. Hence, 40 is 80% of 50.
The correct answer is: D [tex]\(80 \%\)[/tex]
