Start by making the fraction easier to subtract by making the fraction an improper fraction. Multiply 7 by 3 and add it to 2, making the first fraction 23/3. For the second fraction, multiple 3 by 6 and add it to 1 to make it 19/6. 23/3 - 19/6 still cannot be subtracted so you have to multiply the first fraction by 2. 23 times 2 is 46, so the fraction is now 46/6 minus 19/6. 49 - 19 = 30. 30/6 = 5 because six can go into 30 5 times.
