What is 95/29 - 8/12?

Here's how to subtract 8/12 from 95/29:

95
29
8
12

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 95 by 12, and get 1140.

Then we multiply 8 by 29, and get 232.

Next we give both terms new denominators -- 29 × 12 = 348.

So now our fractions look like this:

1140
348
232
348

Step 2

Since our denominators match, we can subtract the numerators.

1140 − 232 = 908

So the answer is:

908
348

Step 3

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

To find out, we try dividing it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

908
348
÷ 2 =
454
174

Let's try dividing by 2 again...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

454
174
÷ 2 =
227
87

Let's try dividing by 2 again...
