What is 21 9/10 as a decimal?
It's very common when learning about fractions to want to know how convert a mixed fraction like 21 9/10 into a decimal. In this step-by-step guide, we'll show you how to turn any fraction into a decimal really easily. Let's take a look!
Before we get started in the fraction to decimal conversion, let's go over some very quick fraction basics. Remember that a numerator is the number above the fraction line, and the denominator is the number below the fraction line. We'll use this later in the tutorial.
When we are using mixed fractions, we have a whole number (in this case 21) and a fractional part (9/10). So what we can do here to convert the mixed fraction to a decimal, is first convert it to an improper fraction (where the numerator is greater than the denominator) and then from there convert the improper fraction into a decimal/
Step 1: Multiply the whole number by the denominator
21 x 10 = 210
Step 2: Add the result of step 1 to the numerator
210 + 9 = 219
Step 3: Divide the result of step 2 by the denominator
219 ÷ 10 = 21.9
So the answer is that 21 9/10 as a decimal is 21.9.
And that is is all there is to converting 21 9/10 to a decimal. We convert it to an improper fraction which, in this case, is 219/10 and then we divide the new numerator (219) by the denominator to get our answer.
If you want to practice, grab yourself a pen, a pad, and a calculator and try to convert a few mixed fractions to a decimal yourself.
