It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. New numerator is 3 + 2 = 5Ĭ) Write a previous answer (new numerator 5) over the denominator 3. Whole number 1 equally 1 * 3 / 3 = 3 / 3ī) Add the answer from the previous step 3 to the numerator 2. Conversion a mixed number 1 2 / 3 to a improper fraction: 1 2/3 = 1 2 / 3 = 1 Ī) Multiply the whole number 1 by the denominator 3.In other words - seven tenths plus four fifths is three halfs. In the following intermediate step, cancel by a common factor of 5 gives 3 / 2. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 5 = 50. The common denominator you can calculate as the least common multiple of both denominators - LCM(10, 5) = 10. In other words - one half plus one fifth is seven tenths. In the following intermediate step, it cannot further simplify the fraction result by canceling. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 5 = 10. The common denominator you can calculate as the least common multiple of both denominators - LCM(2, 5) = 10.
