[ 1/1 Fraction calculation ]
Question type: Fractional addition
Original question: 2/69+2/71
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 69 and 71 respectively,their least common multiple is 4899
Divide the least common multiple 4899 by the denominator 69 of the first addend to get 71
Multiply the numerator 2 and denominator 69 of the first fraction by 71
Then divide the least common multiple 4899 by the denominator 71 of the second addend to get 69
Multiply the numerator 2 and denominator 71 of the second fraction by 69
Calculation result:
