☆1 fraction calculations
[ 1/1 Fraction calculation ]
Question type: Fractional addition
Original question: 2/5+3/4
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 5 and 4 respectively,their least common multiple is 20
Divide the least common multiple 20 by the denominator 5 of the first addend to get 4
Multiply the numerator 2 and denominator 5 of the first fraction by 4
Then divide the least common multiple 20 by the denominator 4 of the second addend to get 5
Multiply the numerator 3 and denominator 4 of the second fraction by 5
Calculation result:
