To reduce fracions follow these steps:
1. Find a number that can divide both numerator and denominator, for the first fraction 2/4, it can be 2
2. Divide top and bottom by that number (2), then we get:
2÷2 / 4÷2 = 1 / 2
3. Repeat from step 1 until there is no number, greater than 1, that can divide the top and the bottom, in this case, there is not such number.
Then when reduced, the first traction 2/4 we get : 1
