☆4 fraction calculations
[ 1/4 Fraction calculation ]
Question type: Fractional addition
Original question: 1/2+1/5 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 1 and denominator 5 of the second fraction by 2 Calculation result: [ 2/4 Fraction calculation ]
Question type: Fractional subtraction
Original question: 35/11-24/11 Solution:
Calculation result: The calculation result is reduced by 11[ 3/4 Fraction calculation ]
Question type: Fractional addition
Original question: 1/2+1/6 Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 2 and 6 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 6 of the second addend to get 1
Multiply the numerator 1 and denominator 6 of the second fraction by 1 Calculation result: The calculation result is reduced by 2[ 4/4 Fraction calculation ]
Question type: Fractional subtraction
Original question: 13/15-11/30 Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 15 and 30 respectively,their least common multiple is 30
Divide the least common multiple 30 by the denominator 15 of the minuend to get 2
Multiply the numerator 13 and denominator 15 of the subtracted number by 2
Then divide the least common multiple 30 by the denominator 30 of the subtraction to get 1
Multiply the subtracted numerator 11 and denominator 30 by 1 at the same timeCalculation result: The calculation result is reduced by 15Your problem has not been solved here? Please go to the Hot Problems section!
