21/2 to a mixed number

In order to convert our improper fraction 21/2 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 [2] goes into the numerator [21]. To do this we divide the numerator by the denominator:

2. Find the New Numerator. Our new numerator is equal to the remainder from previous step [1].

You may also calculate a remainder by using the whole number we calculated in the first step [10] and multiplying it by the original denominator [2]. And then subtract the result from the original numerator [21]:

3. Get our mixed number. To complete our mixed number we need to take the new numerator from previous step [1] and put it above the original denominator [2], and then put the whole number [10] before it

That's it! We have successfully converted the improper fraction 21/2 to the mixed number 10 1/2.
