Solving fractions with different denominators
WebRe-write the fraction using the answer from step 2 above (5) as the numerator and the least common denominator (15) as the denominator. (1/3 = 5/15) Repeat the steps above for all additional fractions in the equation. (15 divided by 5 = 3; 3 x 2 = 6; 2/5 = 6/15) Finally, use the like fractions to solve the equation by adding or subtracting the ... WebIf a pair of fractions have different denominators but those denominators are in the same times table, you need to change one of the denominators so that they are the same. For example, in ¾ + 2/12, you can multiply the denominator 4 by 3 and do the same to the numerator to make 3/12. The calculation will then be 3/12 + 2/12.
