Q:

What is 31/12 as a percent?

Accepted Solution

A:
Solution: 31/12 as a percent is 258.333% Methods Method 1 – Converting 31/12 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 31/12, we could say that the value is 31 portions, out of a possible 12 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 12 = 8.333 \frac{100}{12} = 8.333 12 100 ​ = 8.333 We can then adjust the whole fraction using this number, like so: 31 ∗ 8.333 12 ∗ 8.333 = 258.333 100 \frac{31*8.333}{12*8.333} = \frac{258.333}{100} 12 ∗ 8.333 31 ∗ 8.333 ​ = 100 258.333 ​ Reading this as a fraction, we can say that we have 258.333 portions of a possible 100 portions. Re-writing this as a percentage, we can see that 31/12 as a percentage is 258.333% Method 2 – Converting 31/12 Into a Percentage Using Decimals: Another way we can convert 31/12 into a percentage is to first convert 31/12 into a decimal. We can do this by simply dividing the numerator by the denominator: 31 12 = 2.583 \frac{31}{12} = 2.583 12 31 ​ = 2.583 Once we have the answer, we can multiply the new decimal by 100 to get the percentage: 2.583 × 100 = 258.333 As you can see, we get the same answer as the first method and find that 31/12 as a percentage is 258.333%. Now you know of two different ways to convert 31/12 into a percentage! While converting using a decimal takes fewer steps, you first need to master converting fractions into decimals.
