Adding and subtracting mixed numbers.

Please finish these questions. The answer must be reduced to lowest terms!

1. 3 2/5 + 6 1/5=

2. 4 2/5 + 1/10=

3. 2 3/12 + 2 3/6=

4. 5 3/9 + 2 1/3=

5. 7 5/6 + 3 1/18=

6. 5 3/4 + 7 2/6=

7. 3 - 1 8/12=

8. 5 - 2/8=

9. 2 5/8 - 1 1/8=

10. 5 7/9 - 2 1/3=

11. 4 5/6 - 1 1/12=

12. 3 3/4 - 12/9=

**Ms. Sue**, Wednesday, December 1, 2010 at 9:10pmI checked your first five answers and they are all wrong. For many of them you have not reduced them to lowest terms.

**Pratigya**, Wednesday, December 1, 2010 at 9:17pmYou must be mistaken because my answer is not 44/5 it is 4= 4 whole and then 4/5. Still if you think they are wrong then how can I fix them which ones do I have to reduce?

**Ms. Sue**, Wednesday, December 1, 2010 at 9:34pm1. 3 2/5 + 6 1/5 = 9 3/5

This site shows you how to reduce or simplify fractions.

**Reiny**, Wednesday, December 1, 2010 at 9:37pmI started at the other end ...

#12 wrong

#11 , 3 9/12 = 3 3/4

#10 correct

#9 , 1 4/8 = 1 1/2

#8 , 4 6/8 = 4 3/4

#7 , 4 1/12 = 1 1/3

#6 , 13 2/24 = 13 1/12

I don't know where you got these questions, but most of them were not in lowest terms to begin with. That is very unconventional.

e.g. #3

2 2/13 + 2 3/6

should have been

2 1/4 + 2 1/2

At this point the result can be obtained mentally.

**Ms. Sue**, Wednesday, December 1, 2010 at 9:43pmPlease study the site I posted. Then reduce numbers 2 through 5.

Reiny helped you on the others.

**Ms. Sue**, Wednesday, December 1, 2010 at 10:21pm1 and 2 and 3 are correct. The other two are wrong.

**Schnitzel**, Wednesday, December 1, 2010 at 10:40pmType them into WolframAlpha . com with a + sign between the whole number and its fraction.

For example,

3 2/5 + 6 1/5 becomes (3+2/5) + (6+1/5)

3 - 1 8/12 becomes (3) - (1+8/12)
