What is 97/75 - 1/11?

What is 97/75 - 1/11?

Here's how to subtract 1/11 from 97/75:

97
75
1
11

Step 1

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 97 by 11, and get 1067.

Then we multiply 1 by 75, and get 75.

Next we give both terms new denominators -- 75 × 11 = 825.

So now our fractions look like this:

1067
825
75
825

Step 2

Since our denominators match, we can subtract the numerators.

1067 − 75 = 992

So the answer is:

992
825

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
