You have to convert the mixed fractions to improper fractions and find a common denominator.
For example:
If you want to subtract 3/4 from 10 2/3, you have to first convert the 10 2/3 to an improper fraction, which would be 32/3. Next you have to find the common denominator for both fractions. 3 x 4 = 12, so 12 is the lowest common denominator; therefore, 3/4 = 9/12 and 32/3 = 128/12.
Now you can perform the operation:
128/12 - 9/12 = 117/12; convert 117/12 to a mixed number by dividing 117 by 12, which is 9 with a remainder of 9; 117/12 becomes 9 9/12 or 9 3/4.

Fractions can be added and subtracted only if they're fractions?
We can only add or subtract fractions if they have the same denominators
How do you add or subtract dissimilar fractions?
You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.
How do you add multiple mixed fractions?
Find a common denominator, add the numerators, simplify if possible.
How do you find the average of a mixed fraction?
Same as any average. Add all the fractions and divide them by the amount of fractions
How do you subtract fractions from whole numbers?
turn the whole number into an inproper fraction by doing this: multiply it by the denominator of the fraction.that answer is your numerator make the fractions denominator the whole number's denominator.then subtract just the numerators.you should have an improper fraction as your final answer, so turn that into a mixed number.
