☆1 fraction calculations
[ 1/1 Fraction calculation ]
Question type: Fractional addition
Original question: 7/15+6/11
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 15 and 11 respectively,their least common multiple is 165
Divide the least common multiple 165 by the denominator 15 of the first addend to get 11
Multiply the numerator 7 and denominator 15 of the first fraction by 11
Then divide the least common multiple 165 by the denominator 11 of the second addend to get 15
Multiply the numerator 6 and denominator 11 of the second fraction by 15
Calculation result:
