To convert a fraction to a percentage, you follow a simple process. In this case, we want to find out what 9 out of 10 (which can be expressed as 9/10) is as a percentage.
First, divide the numerator (the top number) by the denominator (the bottom number):
9 ÷ 10 = 0.9
Next, to convert this decimal into a percentage, you multiply by 100:
0.9 × 100 = 90
So, 9 out of 10 equals 90 percent.
This means that if you have a group of 10, 9 members represent 90% of that group.
In summary, 9 out of 10 as a percentage is 90%.
