What is 79/77 as a percent?

Accepted Solution

A:
Solution: 79/77 as a percent is 102.597% Methods Method 1 – Converting 79/77 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 79/77, we could say that the value is 79 portions, out of a possible 77 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 77 = 1.299 \frac{100}{77} = 1.299 77 100 ​ = 1.299 We can then adjust the whole fraction using this number, like so: 79 ∗ 1.299 77 ∗ 1.299 = 102.597 100 \frac{79*1.299}{77*1.299} = \frac{102.597}{100} 77 ∗ 1.299 79 ∗ 1.299 ​ = 100 102.597 ​ Reading this as a fraction, we can say that we have 102.597 portions of a possible 100 portions. Re-writing this as a percentage, we can see that 79/77 as a percentage is 102.597% Method 2 – Converting 79/77 Into a Percentage Using Decimals: Another way we can convert 79/77 into a percentage is to first convert 79/77 into a decimal. We can do this by simply dividing the numerator by the denominator: 79 77 = 1.026 \frac{79}{77} = 1.026 77 79 ​ = 1.026 Once we have the answer, we can multiply the new decimal by 100 to get the percentage: 1.026 × 100 = 102.597 As you can see, we get the same answer as the first method and find that 79/77 as a percentage is 102.597%.
