Adding Fractions w/Explanations

1/2 + 5/10

1 (work on the first fraction [1/2] separately first and multiply its numbers so the denominator is 10: 1/2 x 5/5 becomes 5/10; then add the numerators together: 5 + 5 = 10; 10/10 is 1.)

3/5 + 4/10

10/10, which is 1. (work on the first fraction [3/5] separately first and multiply its numbers so the denominator is 10: 3/5 x 2/2 becomes 6/10; then add the numerators together: 6 + 4 = 10; 10/10 can be reduced to 1.)

6 1/2 + 4 3/5

11 1/10

2 3/16 + 3 5/64 + 5 3/32

11 23/64 : First change denominator to 64ths of an inch. Change 2 3/16 to 2 12/64 + 3 5/64 + 5 6/64 = 11 23/64

2/3 + 1/4

11/12 (work on each fraction separately first and multiply the numbers so the denominator is 12. 2/3 x 4/4 becomes 8/12; 1/4 x 3/3 becomes 3/12; then add the numerators together: 8 + 3 = 11)

8/9 + 1/3

11/9, or 1 2/9. (work on the second fraction [1/3] separately first and multiply its numbers so the denominator is 9: 1/3 x 3/3 becomes 3/9; then add the numerators together: 8 + 3 = 11)

6/7 + 2/28

13/14 (work on the first fraction [6/7] separately first and multiply its numbers so the denominator is 28: 6/7 x 4/4 becomes 24/28; then add the numerators together: 24 + 2 = 26; 26/28 can be reduced to 13/14 if you divide by two.)

2 5/8 +7 3/16 +1 3/32 + 4 7/64

15 1/64 : Convert to the common denominator of 64ths of an inch. 2 5/8 = 2 40/64, 7 3/16 = 7 12/ 64, 1 3/32 = 1 6/64. Next Add the fractions 40/64 + 12/64 +6/64 + 7/64 = 65/64 or 1 1/64 Then add the whole numbers 2 + 7 + 1 + 4 = 14. Last add the sum of whole numbers which is 14 to the sum of the fractions which is 1 1/64 So your final answer is 14 + 1 1/64 = 15 1/64.

11/17 + 5/17

16/17 (since the denominators are already the same, you can simply add the numerators together: 11 +5 = 16)

9 1/2 + 6 3/4 + 2 1/8

18 3/8 : Convert to a common denominator in this case it would be 8ths of an inch. So 9 1/2 would = 9 4/8, 6 3/4= 6 6/8.Now add the fractions 4/8 +6/8 + 1/8 = 11/8 or 1 3/8 Add the whole numbers 9+ 6+ 2 = 17 Last Add the sum of the fractions which was 1 3/8 to the sum of the whole numbers. 17 + 1 3/8 = 18 3/8

7/8 + 9/8

2 (since the denominators are the same [a "common denominator], add the numerators: 7+9=16. 16/8 = 2)

5/6 + 1 2/3

2 1/2 (the first thing to do is get the second number to have 6 as a denominator. 1 = 6/6 and 2/3 x 2/2 = 4/6. Add all the numerators up: 5+6+4=15. 15/6 is the answer, but that can be simplified back into whole numbers. 12/6 = 2, with 3/6 left over. 3/6 can be reduced to 1/2, so the answer is 2 1/2.

1/4 + 2/4

3/4 (since there is already a "common denominator," you can simply add the numerators together: 1 +2 = 3)

2/8 + 1/4

4/8, which can be reduced to 1/2.

1 2/6 + 7 1/3

8 2/3

1/3 + 1/5

8/15 (To find a common denominator, multiply 3x5 to get 15. 1/3 x 5/5 = 5/15. 1/5 x 3/3 = 3/15. Add the numerators now: 5+3=8. There's your answer: 8/15.

3/8 + 5/8

8/8 or 1. (Since there is already a common denominator, just add the numerators: 3+5=8.)

3/9 + 5/9

8/9 (since there is already a "common denominator," you can simply add the numerators together: 3 +5 = 8)

1 1/16 + 2 1/8 + 4 3/32

First change the denominator to 32nd of an inch. 1 2/32 + 2 4/32 + 4 3/32. Add the numerators 2 + 4 + 3 = 9/32 added to the whole numbers 1+2+4=7 Your Final answer is 7 9/32.

5/8 + 1/2

your common denomintaor should be 16. 5/8 becomes 10/16. 1/2 becomes 8/16. When you add them together you get 18/16 = 1 2/16 which can be simplified to 1 and 1/8.
