Answer: 20/48
(simplified) 5/12
Explanation:
We will use 6/8 - 2/6 for our example
6/8 - 2/6
Multiply the denominator on the right side by the denominator on the left side: 6x8 = 48
Make 48 the denominators on both sides: /48, /48
Now multiply the denominator on the left side with the numerator on the left side: 6x6 = 36
Make the first fraction's numerator 36: 36/48
Now multiply the denominator on the left side by the numerator on the right side: 8x2 = 16
Now make 16 the numerator of the second fraction: 16/48
Now that the denominators are the same, we can subtract!
36/48-16/48 = 20/48
Now to simplify:
divide 20/48 by 4 = 5/12
So the answer is 20/48 and when it is simplified it comes out to 5/12
This is how you subtract fractions with different denominators.
You can use the same method when adding, the only difference is that instead of adding in the last step, you add instead!
