☆1 fraction calculations
[ 1/1 Fraction calculation ]
Question type: Fractional addition
Original question: 2/15+5/9
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 15 and 9 respectively,their least common multiple is 45
Divide the least common multiple 45 by the denominator 15 of the first addend to get 3
Multiply the numerator 2 and denominator 15 of the first fraction by 3
Then divide the least common multiple 45 by the denominator 9 of the second addend to get 5
Multiply the numerator 5 and denominator 9 of the second fraction by 5
