What is 60/48 - 6/12?

What is 60/48 - 6/12?

Here's how to subtract 6/12 from 60/48:

60
48
6
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 60 by 12, and get 720.

Then we multiply 6 by 48, and get 288.

Next we give both terms new denominators -- 48 × 12 = 576.

So now our fractions look like this:

720
576
288
576

Step 2

Since our denominators match, we can subtract the numerators.

720 − 288 = 432

So the answer is:

432
576

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:

432
576
÷ 2 =
216
288

Let's try dividing by 2 again...

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

216
288
÷ 2 =
108
144

Let's try dividing by 2 again...

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

108
144
÷ 2 =
54
72

Let's try dividing by 2 again...

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

54
72
÷ 2 =
27
36

Let's try dividing by 2 again...

Nope! So now we try the next greatest prime number, 3...

Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:

27
36
÷ 3 =
9
12

Let's try dividing by 3 again...

Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:

9
12
÷ 3 =
3
4

Let's try dividing by 3 again...

Nope! So now we try the next greatest prime number, 5...

No good. 5 is larger than 3. So we're done reducing.

There you have it! The final answer is:
60
48
6
12
=
3
