Answer:

Simplifying the same denominators first:

16/5 - 13/5 = 3/5

So, we're brought down to:

3/5 + 30/7 + 3/2

35 goes into 5 and 7, so I'll simply 3/5 + 30/7 next -

7 x (3/5) to get 21/35

5 x (30/7) to get 150/35

Now add the two to get 171/35

(150+21=171)

Finally find a common denominator for 35 and 2.

(35x2=70)

2 x (171/35) --> 342/70

35 x (3/2) --> 105/70

Add up 342+105 to get 447 & put over 70.

Answer is 447/70

(It can't be simplified any further than this.)

Hope this helps!
