Answer :
To find out what percent 18 is out of 20, follow these steps:
1. Understand the relationship: We are asked to determine the percentage of a part (18) in relation to the whole (20).
2. Set up the formula for percentage:
[tex]\[
\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100
\][/tex]
3. Plug in the values: Use the given numbers, where the part is 18 and the whole is 20:
[tex]\[
\text{Percentage} = \left( \frac{18}{20} \right) \times 100
\][/tex]
4. Perform the division:
[tex]\[
\frac{18}{20} = 0.9
\][/tex]
5. Multiply by 100 to convert to a percentage:
[tex]\[
0.9 \times 100 = 90
\][/tex]
Therefore, 18 is 90% of 20. So the correct answer is 90%.
