Here's how to subtract 6/12 from 5/10:
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 5 by 12, and get 60.
Then we multiply 6 by 10, and get 60.
Next we give both terms new denominators -- 10 × 12 = 120.
So now our fractions look like this:
Since our denominators match, we can subtract the numerators.
60 − 60 = 0
So the answer is:
|Zero divided by anything is just zero. So that's the final answer:|
