Good old LCMs! 1/6 = 5/30, 3/10 = 9/30 so the answer is -4/30 ie -2/15
This is very similar to addition. You first have to convert to a common denominator.For example, in 3/4 - 1/2: First convert everything to fourths: 3/4 - 2/4. Next subtract the numerators: (3-2)/4 = 1/4.This is very similar to addition.

3, 6, 9, and 12 are the first four integer multiples (products of 1, 2, 3, 4). 6, 9, 12, and 15 are the first four prime multiples (products of 2, 3, 4, 5).
All You Have To Do Is First Add 1 Then 2 More Then 3 More Then 4 More.
