[ 1/1 Fraction calculation ]
Question type: Fractional addition
Original question: 38/211+64/137
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 211 and 137 respectively,their least common multiple is 28907
Divide the least common multiple 28907 by the denominator 211 of the first addend to get 137
Multiply the numerator 38 and denominator 211 of the first fraction by 137
Then divide the least common multiple 28907 by the denominator 137 of the second addend to get 211
Multiply the numerator 64 and denominator 137 of the second fraction by 211
Calculation result:
