[ 1/6 Fraction calculation ]
Question type: Fractional addition
Original question: 1/2+3/5 Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 2 and 5 respectively,their least common multiple is 10
Divide the least common multiple 10 by the denominator 2 of the first addend to get 5
Multiply the numerator 1 and denominator 2 of the first fraction by 5
Then divide the least common multiple 10 by the denominator 5 of the second addend to get 2
Multiply the numerator 3 and denominator 5 of the second fraction by 2 Calculation result: [ 2/6 Fraction calculation ]
Question type: Fractional addition
Original question: 12/6+3/7 Solution:
The first fraction is reduced by 6
Divide two fractions with defferent denominators:The denominators of two fractions are 1 and 7 respectively,their least common multiple is 7
Divide the least common multiple 7 by the denominator 1 of the first addend to get 7
Multiply the numerator 2 and denominator 1 of the first fraction by 7
Then divide the least common multiple 7 by the denominator 7 of the second addend to get 1
Multiply the numerator 3 and denominator 7 of the second fraction by 1 Calculation result: [ 3/6 Fraction calculation ]
Question type: Fractional addition
Original question: 4/4+5/5 Solution:
The first fraction is reduced by 4
The second fraction is reduced by 5 Calculation result: [ 4/6 Fraction calculation ]
Question type: Fractional subtraction
Original question: 18/2-7/4 Solution:
Reduce the minuend by 2
Divide two fractions with defferent denominators:The denominators of two fractions are 1 and 4 respectively,their least common multiple is 4
Divide the least common multiple 4 by the denominator 1 of the minuend to get 4
Multiply the numerator 9 and denominator 1 of the subtracted number by 4
Then divide the least common multiple 4 by the denominator 4 of the subtraction to get 1
Multiply the subtracted numerator 7 and denominator 4 by 1 at the same timeCalculation result: [ 5/6 Fraction calculation ]
