☆1 fraction calculations
[ 1/1 Fraction calculation ]
Question type: Fractional subtraction
Original question: 3/5-7/12
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 5 and 12 respectively,their least common multiple is 60
Divide the least common multiple 60 by the denominator 5 of the minuend to get 12
Multiply the numerator 3 and denominator 5 of the subtracted number by 12
Then divide the least common multiple 60 by the denominator 12 of the subtraction to get 5
Multiply the subtracted numerator 7 and denominator 12 by 5 at the same time
