Q:

What is 9/81 as a percent?

Accepted Solution

A:
Solution: 9/81 as a percent is 11.111% Methods Method 1 – Converting 9/81 Into a Percentage: First, let’s go over what a fraction represents. The number above the line is called the numerator, while the number below the line is called the denominator. The fraction shows how many portions of the number there are, in relation to how many would make up the whole. For instance, in the fraction 9/81, we could say that the value is 9 portions, out of a possible 81 portions to make up the whole. For percentages, the difference is that we want to know how many portions there are if there are 100 portions possible. “Percent” means “per hundred”. For example, if we look at the percentage 25%, that means we have 25 portions of the possible 100 portions. Re-writing this in fraction form, we see 25/100. The first step in converting a fraction to a percentage is to adjust the fraction so that the denominator is 100. To do this, you first divide 100 by the denominator: 100 81 = 1.235 \frac{100}{81} = 1.235 81 100 ​ = 1.235 We can then adjust the whole fraction using this number, like so: 9 ∗ 1.235 81 ∗ 1.235 = 11.111 100 \frac{9*1.235}{81*1.235} = \frac{11.111}{100} 81 ∗ 1.235 9 ∗ 1.235 ​ = 100 11.111 ​ Reading this as a fraction, we can say that we have 11.111 portions of a possible 100 portions. Re-writing this as a percentage, we can see that 9/81 as a percentage is 11.111% Method 2 – Converting 9/81 Into a Percentage Using Decimals: Another way we can convert 9/81 into a percentage is to first convert 9/81 into a decimal. We can do this by simply dividing the numerator by the denominator: 9 81 = 0.111 \frac{9}{81} = 0.111 81 9 ​ = 0.111 Once we have the answer, we can multiply the new decimal by 100 to get the percentage: 0.111 × 100 = 11.111 As you can see, we get the same answer as the first method and find that 9/81 as a percentage is 11.111%. Now you know of two different ways to convert 9/81 into a percentage! While converting using a decimal takes fewer steps, you first need to master converting fractions into decimals.
