What is 60/60 + 3/12?

What is 60/60 + 3/12?

This is how you add

60
60
+
3
12

Step 1

Now we need to make our denominators match.

60 goes into 12 evenly, so we only need to multiply one term to get a common denominator.

Multiply 3 by 5, and get 15, then we multiply 12 by 5 and get 60.

3/12 times 5

We now have a new problem, that looks like this:

60
60
+
15
60

Step 2

Since our denominators match, we can add the numerators.

60 + 15 = 75

That gives us the sum, which is

75
60

Step 3

Now, do we need to simplify this fraction?

First, we attempt to divide it by 2...

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:

75
60
÷ 3 =
25
20

Let's try dividing by that again...

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

Are both the numerator and the denominator evenly divisible by 5? Yes! So we reduce it:

25
20
÷ 5 =
5
4

Let's try dividing by that again...

No good. 5 is larger than 4. So we're done reducing.

There you have it! Here's the final answer to 60/60 + 3/12

60
60
+
3
12
=
5
4
