Take LCM of the the denominators

7 and 8

There LCM = 56

To subtract we should have the common denominators .

For Example - 56 should be our denominator while subtracting so -

5 × 8 = 40

7 × 8 = 56

3 × 7 = 21

8 × 7 = 56

So we have to subtract now as the denominators are same

40 - 21 = 19

56 - 56 = 56

Answer = 19

We dont have to change in mixed fraction as the answer is in proper fraction
