What is 15/60 + 2/4?

Here's how we add

Step 1

Now we need to make our denominators match.

60 goes into 4 evenly, so we only need to multiply one term to get a common denominator.

Multiply 2 by 15, and get 30, then we multiply 4 by 15 and get 60.

This gives us a new problem that looks like so:

Step 2

Since our denominators match, we can add the numerators.

15 + 30 = 45

That gives us an answer of

Step 3

Can this fraction be reduced?

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:

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:

Let's try dividing by that again...

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

There you have it! Here's the final answer to 15/60 + 2/4
