To find out what percent 9 is out of 20, you can use the following formula:
Percentage = (Part / Whole) × 100
In this case, the part is 9 and the whole is 20. Plugging these values into the formula:
Percentage = (9 / 20) × 100
First, divide 9 by 20:
9 ÷ 20 = 0.45
Next, multiply the result by 100 to get the percentage:
0.45 × 100 = 45%
So, 9 out of 20 is 45%.
