+150 This is how I always understood it,
It is just like +, First ignore the whole numbers, for now
now you have: 1/2-2/9
find a common denominator (The bottom number in a fraction)
how many times would you multiply 9 to make it even for 2 to go into? Twice, because that turns into 18. How many times do you need to multiply 2 to get 18? nine times.
The rule is you have to do the same thing to both your Numerator (top number in a fraction) and your denominator, so if your multiplying 9x2 then you have to multiply 2x2 as well. If you do that you end up with 4/18 for the last number. Now if your multiplying the first number by 9. Then you have to multiply 1x9 and 2x9 which leaves you with 9/18
Now your equation is 9/18-4/18. Ignore the 18 for now, what is 9-4? 5 so your answer is 5/18, you cannot reduce that, so now on to your whole numbers:
9-1=8 so just add the two together and you get 8 5/18
I promise you, once you get the hang of it, its not as complicated as I made it seem
