I'm guessing you have some sort of homework to do...

So when you have to show your work, I would recommend doing the following...
1. Change them to improper fractions ( 23/5, 17/7, 181/35)
2. Add these fractions with a common denominator of 35
3. With the common denominator you will be adding (161/35, 85/35, 181/35)
4. You should get 427/35 which should reduce down to
12 2/10=12 1/5.

Double check all of this work for yourself to make sure it's right and that you understand it for your test/homework.

4 3/5 +2 3/7 + 5 6/35

One approach is to convert each mixed number to an improper fraction, find the LCD and convert each term to that LCD, add the resulting numerators, simplify.

To work with smaller numbers, add the whole numbers and then add the fractional parts

4 3/5 + 2 3/7 + 5 6/35
4 + 2 + 5 + 3/5 + 3/7 + 6/35
11 + 3/5 + 3/7 + 6/35

Now just the fractions

3/5 + 3/7 + 6/35 {LCD is 35}

3(7)/5(7) + 3(5)/7(5) + 6/35
21/35 + 15/35 + 6/35
42/35
1 7/35 {add to 11 determined above}

12 7/35
12 1/5

fine the common denominator which in this problem is 35.

Convert to fraction:
23/5 + 17/7 + 181/35
161/35 + 85/35 + 181/35

Add them, convert, and reduce:
427/35 = 12 7/35 = 12 1/5
