I need help with this question subtract and simplify 2/3-41/125

1) Find LCM of the 2 denominators of the 2 fractions. (LCM is the lowest number divisible by both denominators)

3 & 125: LCM = 375

2) Divide LCM by denominator and multiply the result by the numerator then write the answer as the new numerator. Repeat for the second fraction.

for 2/3:  375/3 = 125 * 2 = 250 ----------->  250/375

for 41/125 :   375/125 = 3* 41 = 123 ------------> 123/375

3) Solve using the new fractions.

250/375  -  123/375 = 127/375

4) Simplify if you can, but in this case 127 can not be simplified.
