Then convert each fraction to an equivalent fraction with denominator abcd.
Add and subtract proper and improper fractions with this calculator and see the work involved in the solution.
Take the number you get for each fraction and multiply it by the numerator and denominator of that fraction which will make both denominators equal to the least common multiple.
Suppose you want to add the fractions 34 710.
