Round the mixed fraction to half of whole.
replace each fraction with its closest half or whole
You first have to make the denominators the same. After this, you add the tops normally. Then, you reduce/simplify if needed.

If I had some fractions, I might. But since I don't, I won't.
The sum of two fractions will only be a whole number if the fractions have a common denominator. When the denominators are different, the sum will be a fraction with a different denominator, making it impossible to be a whole number. Thus, estimating the sum of two fractions will generally result in a fraction, not a whole number.
i think you take the problem and turn it in to a improper fraction. estimate. add. Vola!
The same way that you calculate the average for any other numbers. Sum the fractions and divide the total by the number of fractions.
It depends on your level of numerical skill. You can convert the decimal to an approximate fraction and estimate the sum of the two fractions, or you can convert the fraction to an approximate decimal and estimate the sum of the two decimals or, if you are more able you just estimate their sum directly.
find the lowest common denominator
Estimate by rounding to the nearest ten.​ Then, find the sum.221122plus+33554455​_​_The estimated sum is nothing.
First add all the fractions together. Then, divide this sum by the total number of fractions that were in the set. This quotient is your average fraction.

To find the sum of two mixed numbers, turn the mixed numbers into improper fractions (multiply the base with the denominator and add the numerator), then add the two fractions. To add the two fractions, find the LCD (lowest common denominator) and add the two numerators, but leave the denominators the same.
