So let's get ourselves a common denominator. It looks like a common denominator right over here. It could be 4. So this is equal to 5 is the same thing as 20 over 4 minus 25 over 4 and then plus 30 over 4. So 20 plus 30 is 50 minus 25 is 25. So this is equal to 25 over 4. And 25 over 4 is the same thing as 6 and 1 fourth.
