☆4 fraction calculations
[ 1/4 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[ 2/4 Fraction calculation ]
Question type: Fractional subtraction
Original question: 3/5-1/2 Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 5 and 2 respectively,their least common multiple is 10
Divide the least common multiple 10 by the denominator 5 of the minuend to get 2
Multiply the numerator 3 and denominator 5 of the subtracted number by 2
Then divide the least common multiple 10 by the denominator 2 of the subtraction to get 5
Multiply the subtracted numerator 1 and denominator 2 by 5 at the same timeCalculation result: [ 3/4 Fraction calculation ]
Question type: Fractional addition
Original question: 4/8+6/10 Solution:
The first fraction is reduced by 4
The second fraction is reduced by 2 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: [ 4/4 Fraction calculation ]
Question type: Fractional subtraction
Original question: 8/3-6/4 Solution:
Reduce the subtractor by 2 Divide two fractions with defferent denominators:The denominators of two fractions are 3 and 2 respectively,their least common multiple is 6
Divide the least common multiple 6 by the denominator 3 of the minuend to get 2
Multiply the numerator 8 and denominator 3 of the subtracted number by 2
Then divide the least common multiple 6 by the denominator 2 of the subtraction to get 3
Multiply the subtracted numerator 3 and denominator 2 by 3 at the same timeCalculation result: Your problem has not been solved here? Please go to the Hot Problems section!
