yeah whats
1 and 4 sevenths
plus
3 and 2 thirds?
+rep

5 and 5/21

5 and 5 twenty firsts
lol
just beat me

1 4/7 + 3 2/3

Change it into a top heavy fraction:

1 4/7 = 11/7
3 2/3 = 11/3

Convert the numerators to both be equal, and do the same thing to the denominator, in this case, we shall convert the numerator to 21.

11/7 = 33/21
11/3 = 77/21

Add them, 33/21 + 77/21 = 110/21

Now change it into a proper fraction

21 x 5 = 105

110 - 105 = 5

Answer = 5 5/21

Got bored so I thought I should post an explanation on how you do it. Hope you've learnt how ;]

My answer is 5 5/21, I think not for sure, read other posts.

I tried my best thats what counts :D

Christ, how on earth did you work that out?

Im rather rubbish at maths tbh.
Gonna fail!

This way seems easier than the above imo... :

1 4/7
3 2/3

3x7 = 21 (LCD)

1 4/21
3 2/21

4x3 = 12
2x7 = 14

1 12/21
3 14/21

1+3 = 4

12+14 = 26

26/21 = 1 5/21
4 + 1 = 5

Answer = 5 5/21

you find the lowest common multiple and make it into a top heavy fraction, then you simplify it so you have a whole number and a bottom heavy fraction
