Answer:
1. 1
2. 5/8
3. 3/4
4. 7/8
5. 5/8
Step-by-step explanation:
1. The denominators are the same, so just add the top numbers (the numerator), 1/7 + 6/7 = 7/7, which is 1.
2. The denominators are the same, so just add the top numbers (the numerator), 7/16+3/16=10/16. 10/16 can be divided by 2 to get 5/8.
3. 1/6=2/12. So, the new problem is 2/12+7/12. Add the numbers, and you get 9/12. Divide the top and bottom by 3, and your answer is 3/4.
4. 3/4=6/8. The new problem is 6/8+1/8. This is 7/8.
5. 1/4=2/8. The new problem is 2/8+3/8. 2+3 is 5, so your answer is 5/8.
