Multiply 1/3 by 4 and 1/4 by 3 so the denominators are both 12. Then you have 4/12 and 3/12 so add those two fractions to get 7/12. if all three days equals 12/12, and Monday plus Tuesday equals 7/12, the remainder of the pay will be 5/12 on Wednesday.
All you have to do is make 1 into a fraction 4/4+1/4 makes the 8 servings find and equivilent fraction so 8/8+2/8= 8 servings half it 4/8+1/8= 4 servings so half a cup and an eighth of a cup or 5/8 of a cup hope this helped you have a great day!!
