Answer 1

8/12 - 3/12

5/12

Step-by-step explanation:

The given expression is

`(2)/(3)-(1)/(4)`

We can solve this subtraction as follows

`(2)/(3)-(1)/(4)=(2(4)-3(1))/(3(4))=(8-3)/(12)=(5)/(12)`

Therefore, the expression is also equivalent to 5/12.

For the other options, we can solve the subtractions, if one option is equal to 5/12, the option is correct

`\begin{gathered} (6)/(12)-(4)/(12)=(6-4)/(12)=(2)/(12) \\ \\ (8)/(12)-(3)/(12)=(8-3)/(12)=(5)/(12) \\ \\ (2)/(7)-(1)/(7)=(2-1)/(7)=(1)/(7) \\ \\ (1)/(7)=(1)/(7) \\ \\ (2)/(12)=(2)/(12) \\ \\ (5)/(12)=(5)/(12) \end{gathered}`

Therefore, the correct options are

8/12 - 3/12

5/12
