80/21 to a mixed number
How to write 80/21 as a Mixed Number?
Since we have an improper fraction (the numerator [80] is greater than the denominator [21]), we can convert it into a mixed number (a combination of a whole number and a proper fraction):
Steps to convert 80/21 to a mixed number
In order to convert our improper fraction 80/21 to a mixed number, we need to follow three basic steps:
1. Find the whole number. First we need to calculate how many times the denominator [21] goes into the numerator [80]. To do this we divide the numerator by the denominator:
80 ÷ 21 = 3.81 = 3
(Quotient of 3 and a remainder of 17)
2. Find the New Numerator. Our new numerator is equal to the remainder from previous step [17].
You may also calculate a remainder by using the whole number we calculated in the first step [3] and multiplying it by the original denominator [21]. And then subtract the result from the original numerator [80]:
80 - (3 × 21)
=80 - 63 = 17
3. Get our mixed fraction. To complete our mixed fraction we need to take the new numerator from previous step [17] and put it above the original denominator [21], and then put the whole number [3] before it
That's it! We have successfully converted the improper fraction 80/21 to the mixed number 3 17/21.
