Answer:
1/2
Explanation:
To simplify, you have to make all of the denominators (bottom numbers) the same because you have to add and subtract. All of the fractions have common denominators of 12. 1/12 does not need to be changed, but 3/4 and 1/3 do need to be. To get to the common denominator, multiply by whichever number gets you to the number (in this case the number is 12).
3/4 x 3 = 9/12
1/3 x 4 = 4/12
Now we can simplify a lot easier. Substitute the equivalent fractions with the original ones.
9/12-4/12+1/12
In the order of operations, you subtract first if the operation comes before addition. Because that is the case here, we have to subtract 9/12-4/12.
9/12-4/12=5/12
Finally, add 1/12.
5/12+1/12=6/12.
The final answer is 6/12, but you can simplify it further to 1/2.
