Consider a simple example. Three fractions — 2/3, 1/5, and 3/8.
Multiplying these fractions does not require any special work be done. Just multiply numerators and multiply denominators and there is your answer. It may need to be reduced, but that’s it.
2/3 x 1/5 x 3/8 = 6/120 = 1/20
Adding these fractions requires finding the LCM of the denominators and then expressing all the fractions with that common denominator before adding the numerators.
2/3 + 1/5 + 3/8
LCM of 3, 5, and 8 is 120
80/120 + 24/120 + 45/120 = 149/120
