Ok, so this is a subtraction problem with fractions. The first step is to write the equation you need to make.
12 1/2 - 8 2/3
Next would be to change the mixed fractions to improper fractions.
25/2 - 26/3
Now, we need to find a common denomintor, since we can't just subtract like it is now. The Lowest Common Denominator would be 6 because 2*3 = 6. So we need to multiply the numerator and the denominator of both fractions, so that they will have the same denominator.
3( 25/2 ) - 2( 26/3 )
75/6 - 52/6
Now we just subtract the numerators and leave that new answer over the same denominator.
75/6 - 52/6 = 23/6
If it asks to simplify into fraction, we can put it as,
3 5/6
