What is 18/22 as a percent?

Accepted Solution

Solution: 18/22 as a percent is 81.818% Methods Method 1 – Converting 18/22 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 18/22, we could say that the value is 18 portions, out of a possible 22 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 22 = 4.545 \frac{100}{22} = 4.545 22 100 ​ = 4.545 We can then adjust the whole fraction using this number, like so: 18 ∗ 4.545 22 ∗ 4.545 = 81.818 100 \frac{18*4.545}{22*4.545} = \frac{81.818}{100} 22 ∗ 4.545 18 ∗ 4.545 ​ = 100 81.818 ​ Reading this as a fraction, we can say that we have 81.818 portions of a possible 100 portions. Re-writing this as a percentage, we can see that 18/22 as a percentage is 81.818% Method 2 – Converting 18/22 Into a Percentage Using Decimals: Another way we can convert 18/22 into a percentage is to first convert 18/22 into a decimal. We can do this by simply dividing the numerator by the denominator: 18 22 = 0.818 \frac{18}{22} = 0.818 22 18 ​ = 0.818 Once we have the answer, we can multiply the new decimal by 100 to get the percentage: 0.818 × 100 = 81.818 As you can see, we get the same answer as the first method and find that 18/22 as a percentage is 81.818%.
