Question type: Fractional subtraction
Original question: 3/15200-3/11200
Solution:
Divide two fractions with defferent denominators:The denominators of two fractions are 15200 and 11200 respectively,their least common multiple is 212800
Divide the least common multiple 212800 by the denominator 15200 of the minuend to get 14
Multiply the numerator 3 and denominator 15200 of the subtracted number by 14
Then divide the least common multiple 212800 by the denominator 11200 of the subtraction to get 19
Multiply the subtracted numerator 3 and denominator 11200 by 19 at the same time
Calculation result:
The calculation result is reduced by 5
