PEDMAS
The rule is Paranthesis First
|7-(24÷|3-6|)|
|7-(24÷|-3|)|
Now we have to get the -3 outside the 2 Lines but the lines are saying that if the number inside is negative when you get it outside it has to be positive.
|7-(24÷3)|-
|7-(8)|
|7-8|
|-1|
= 1
So we want to write a fraction that is less than 5/6 and has a denominator of 8. So lets start from 1/1 that is greater then 5/6 and doesn't have 8 as a denominator. Lets take one half from 1/1 and well get 1/2.
