1. If 6 problems equals 3/13 of the problems, we know that half of how many problems you do is equal to that equation.
2. Multiply 13 x 2. This is because if 6 is twice as . much of the total assignment to complete, you want to multiply the amount of the total assignment by 2.
3. So, now you have 6/26. All you have to do is subtract 6 from 26. This leaves you with 20. 20 is your final answer.
