Answer 1

Answer:

(i)

Converting Mixed fraction into improper fraction

5 1/5 = 26/5

2 1/7 = 15/7

So , 26/5 + 15/7

Taking LCM of 5 and 7 which is 35

= 182/35 + 75/35

= 257/35

We can also write 257 / 35 as 7 12/35

So , 5 1/5 + 2 1/7 = 7 12/35

(ii)

Converting Mixed fraction into improper fraction

3 1/5 = 16/5

2 1/3 = 7/3

So , 16/5 + 7/3

Taking LCM of 5 and 3 which is 15

= 48/15 + 35/15

= 83/15

We can also write 83/15 as 5 8/15

So , 3 1/5 + 2 1/3 = 5 8/15
