Question

Find the difference in simplest form for 3/5-1/7

Answer 1

3/5 - 1/7

Find the LCM of 5 and 7 to find equivalent fractions for both fractions

LCM = 35

3/5 = 21/35

1/7 = 5/35

So 21/35 - 5/35 = 16/35

I'm pretty sure that's the simplest form because I can't think of a common factor of 16 and 35 by which to reduce it further.
