What is 3/4 + 2/8?

What is 3/4 + 2/8?

This is how we add

3
4
+
2
8

Step 1

We have to make sure the denominators are equal.

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

Multiply 3 by 2, and get 6, then we multiply 4 by 2 and get 8.

3/4 times 2

This gives us a new problem that looks like so:

6
8
+
2
8

Step 2

Since our denominators match, we can add the numerators.

6 + 2 = 8

That gives us an answer of

8
8

Step 3

Can this fraction be reduced?

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

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

8
8
÷ 2 =
4
4

So far so good... let's try to divide by that number again.

No good. 2 is larger than 1. So we're done reducing.

And we're done! Here's the final answer to 3/4 + 2/8

3
