Answer:
(In order from top to bottom) 1/2, 3/14, 1/10, 0
Explanation:
1. 5/6 - 1/3
Make the denominators have matching numbers. The simplest way to do this is to multiple 1/3 by two. This will result in 2/6.
The new equation will look like: 5/6 - 2/6. Then you just subtract the numerators and simplify. 3/6 -> 1/2
2. 5/7 - 1/2
Again, you have to make the denominators have matching numbers. This is a little more complicated. Find the least common multiple. The LCM should be 14, so you'll have to multiply the first fraction by 2, and the second fraction by 7.
It will look like 10/14 - 7/14. Follow the steps from the previous problem to get your answer. In this case, you cannot simplify your answer.
The last two problems will follow the same steps as the first two.
