Q:

What is 40/86 as a percent?

Accepted Solution

A:
Solution: 40/86 as a percent is 46.512% Methods Method 1 – Converting 40/86 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 40/86, we could say that the value is 40 portions, out of a possible 86 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 86 = 1.163 \frac{100}{86} = 1.163 86 100 ​ = 1.163 We can then adjust the whole fraction using this number, like so: 40 ∗ 1.163 86 ∗ 1.163 = 46.512 100 \frac{40*1.163}{86*1.163} = \frac{46.512}{100} 86 ∗ 1.163 40 ∗ 1.163 ​ = 100 46.512 ​ Reading this as a fraction, we can say that we have 46.512 portions of a possible 100 portions. Re-writing this as a percentage, we can see that 40/86 as a percentage is 46.512% Method 2 – Converting 40/86 Into a Percentage Using Decimals: Another way we can convert 40/86 into a percentage is to first convert 40/86 into a decimal. We can do this by simply dividing the numerator by the denominator: 40 86 = 0.465 \frac{40}{86} = 0.465 86 40 ​ = 0.465 Once we have the answer, we can multiply the new decimal by 100 to get the percentage: 0.465 × 100 = 46.512 As you can see, we get the same answer as the first method and find that 40/86 as a percentage is 46.512%.
