Question type: Fractional addition
Original question: 1/1+1/2 Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 1 and 2 respectively,their least common multiple is 2
Divide the least common multiple 2 by the denominator 1 of the first addend to get 2
Multiply the numerator 1 and denominator 1 of the first fraction by 2
Then divide the least common multiple 2 by the denominator 2 of the second addend to get 1
Multiply the numerator 1 and denominator 2 of the second fraction by 1 Calculation result: [ 2/7 Fraction calculation ]
Question type: Fractional addition
