What is 21/34 as a percent?

Accepted Solution

Solution: 21/34 as a percent is 61.765% Methods Method 1 – Converting 21/34 Into a Percentage: In a fraction, the number above the line is called the numerator, and the number below the line is called the denominator. The fraction shows how many “pieces” of the number there are, compared to how many there are possible. For instance, in the fraction 21/34, we could say that there are 21 pieces out of a possible 34 pieces. “Percent” means “per hundred”, so for percentages we want to know how many pieces there are if there are 100 pieces possible. For example, if we look at the percentage 75%, that means we have 75 pieces of the possible 100. Re-writing this in fraction form, we see 75/100. When converting the fraction into a percent, the first step is to adjust the fraction so that there will be 100 pieces possible (the denominator needs to be changed to 100). To do this, you first divide 100 by the denominator: 100 34 = 2.941 \frac{100}{34} = 2.941 34 100 ​ = 2.941 We can then adjust the whole fraction using this number, like so: 21 ∗ 2.941 34 ∗ 2.941 = 61.765 100 \frac{21*2.941}{34*2.941} = \frac{61.765}{100} 34 ∗ 2.941 21 ∗ 2.941 ​ = 100 61.765 ​ As you can see, there are 61.765 pieces out of a possible 100 pieces. Re-writing this as a percentage, we can see that 21/34 as a percentage is 61.765%. Method 2 – Converting 21/34 Into a Percentage Using Decimals: If you already know how to convert a fraction into a decimal, you can also use this method as a step for converting to a percentage. Let’s show you how. First, convert the fraction into a decimal by dividing the numerator by the denominator: 21 34 = 0.618 \frac{21}{34} = 0.618 34 21 ​ = 0.618 If we multiply the decimal by 100, we will get the percentage: 0.618 * 100 = 61.765 Now we can see that 21/34 as a percentage is 61.765. Try out both methods and see which one works best for you! Some people like to use the first method, while others will prefer to use the decimal method. There is no “best” way to convert fractions into percentages, just choose the method that works for you.
