How to add Fractions?

Okay okay, I know this is kind of Elementary school ; But I just recently started school again (I was out of school for about a year) and I forgot how i’m suppose to add fractions along with Whole numbers. (Example : 3 1/4 + 8 7/8 = ? )

Onto the question. I’m basically correcting a test I took. The question was : ‘Mrs. Largo has 3 5/6 of yarn on a spool. She adds 2 3/4 yards to the spool. How many yards of yarn will she have on the spool?’ I didn’t know how to do this, So i just went on and added 3 5/6 + 2 3/4 = 5 8/10. I just added everything.

Well, I got the answer wrong. I’ve tried looking up how to do this, but nothing is seems to help. Can anyone explain how i’m suppose to do this?

Answer #1

Convert the fractions to irregulars, then find a common denominator. Then add the fractions together So, 3 5/6 would be 23/6, then 2 3/4 would be 11/4 To find the common denominator, simply multiply the denominators. 6x4=24 You then multiply the numerators by whatever you multiplied the denominators by, so you do 11x6=66 and 23x4=92 So you would have 66/24 + 92/24 You then add the numerators, and convert 158/24 back to a mixed number

Answer #2

first change those mixed numbers into improper fractions (here’s a link on how to do that http://funadvice.com/r/3o57p97o8e. so 3 5/6 would be 23/6, and 8 7/8 would be 11/4. now you have to find a common denominator between 23/6 and 11/4, which is 24. so put 24 as both the denominators. 6 times 4 is 24, so you have to multiply 23 times 4 which is 92. 4 times 6 is 24, so you have to multiply 11 times 6 which is 66. now you have 92/24 + 66/24 which equals 158/24. so the final answer after you convert 158/24 back into a mixed number is 6 14/24.

Answer #3

Right, So then you simplify that into 6 7/12. Alright, I get it now!

Thanks a ton.
