☆4 fraction calculations
[ 1/4 Fraction calculation ]
Question type: Fractional addition
Original question: 1/2+1/3 Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 2 and 3 respectively,their least common multiple is 6
Divide the least common multiple 6 by the denominator 2 of the first addend to get 3
Multiply the numerator 1 and denominator 2 of the first fraction by 3
Then divide the least common multiple 6 by the denominator 3 of the second addend to get 2
Multiply the numerator 1 and denominator 3 of the second fraction by 2 Calculation result: [ 2/4 Fraction calculation ]
Question type: Fractional multiplication
Original question: 5/6×3/5 Solution:
Divide the numerator of the first fraction and the denominator of the second fraction by 5
Divide the numerator of the second fraction and the denominator of the first fraction by 3 Calculation result: [ 3/4 Fraction calculation ]
Question type: Fractional division
Original question: 6/7÷2/7 Solution:
Calculation result: The calculation result is reduced by 14[ 4/4 Fraction calculation ]
Question type: Fractional subtraction
Original question: 2/3-1/5 Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 3 and 5 respectively,their least common multiple is 15
Divide the least common multiple 15 by the denominator 3 of the minuend to get 5
Multiply the numerator 2 and denominator 3 of the subtracted number by 5
Then divide the least common multiple 15 by the denominator 5 of the subtraction to get 3
Multiply the subtracted numerator 1 and denominator 5 by 3 at the same timeCalculation result: Your problem has not been solved here? Please go to the Hot Problems section!
