What is 45/54 as a percent?

Accepted Solution

Solution: 45/54 as a percent is 83.333% Methods Method 1 – Converting 45/54 Into a Percentage: In a fraction, we can see how many “pieces” of a number are present (in the numerator) compared to how many pieces would make up the whole (the denominator). “Percent” means “per hundred”, which is like asking the question “how many pieces would there be if there were 100 pieces possible?” For example, if we look at the percentage 50%, that means we have 50 pieces of the possible 100. Re-writing this in fraction form, we see 50/100. We can start the process of converting a fraction into a percent, by figuring out how to adjust the fraction so that the denominator will be 100. First, divide 100 by the denominator: 100 54 = 1.852 \frac{100}{54} = 1.852 54 100 ​ = 1.852 Then we can multiply both the numerator and denominator by this number: 45 ∗ 1.852 54 ∗ 1.852 = 83.333 100 \frac{45*1.852}{54*1.852} = \frac{83.333}{100} 54 ∗ 1.852 45 ∗ 1.852 ​ = 100 83.333 ​ This works because multiplying both the numerator and the denominator by the same number is like multiplying it by 1. (1.852 / 1.852 = 1) Re-writing the result as a percentage, we can see that 45/54 as a percentage is 83.333%. Method 2 – Converting 45/54 Into a Percentage Using Decimals: Another common way to convert a fraction into a percentage is to first convert the fraction into a decimal. To convert 45/54 into a percentage, you would first convert 45/54 into a decimal by dividing the numerator by the denominator: 45 54 = 0.833 \frac{45}{54} = 0.833 54 45 ​ = 0.833 Once you have converted the fraction into a decimal, you can simply multiply by 100 to get the percentage: 0.833 x 100 = 83.333 And there you go! Now we can see that 45/54 as a percentage is 83.333%, the same way we did with the first method. Now you know of two ways you can convert 45/54 into a percentage.
