You have to perform the subtraction completely to figure it out.

Answer 9

@Hero i don't know how

Answer 10

Suppose you had to subtract \(\dfrac{24}{5} - 4\). How would you do it?

Answer 11

@Hero make it 24/5 - 4/1?

Answer 12

And then what would you do?

Answer 13

@Hero it would be 20/4?

Answer 14

Hmmm. So basically, what you are saying is you don't know how to subtract regular fractions. You should review how to subtract basic fractions before dealing with algebraic fractions.
