The denominator must be the same, so just think of the LEAST COMMON MULTIPLE, The LCM here is 8, because you can multiply 4 by 2 to get 8.
so when you multiply, you multiply both on the top and on the bottom, so this would be:
3 x 2 / 4 x 2 = 6 / 8
Now you can add or subtract: 6/8 - 1/8 = 5/8
Alright, so since I don't have an example question, I will make one up.
there are 8 coins in total. there are 6 dimes. What is the fraction of dimes to coins.
you would put the amount of dimes on the top and the total on the bottom.
Answer: 6/8 which can be simplified to 3/4
Or another Example:
There are 12 pieces in the pizza. Billy took 4. what is the fraction of the slices left.
it would be 4-12= 8
Answer: 8/12 which can be simplified to 4/6 and then to 2/3
Hope that helped.
The correct answer is x=3. Hope this helps!!
The solution to what you put down is 1,3
