What is 32/1 + 4/8?

What is 32/1 + 4/8?

This is how we add

32
1
+
4
8

Step 1

Now we need to make our denominators match.

8 goes into 1 evenly, so we only need to multiply one term to get a common denominator.

Multiply 32 by 8, and get 256, then we multiply 1 by 8 and get 8.

32/1 times 8

This gives us a new problem that looks like so:

256
8
+
4
8

Step 2

Since our denominators match, we can add the numerators.

256 + 4 = 260

So what's the answer so far?

260
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:

260
8
÷ 2 =
130
4

Let's try dividing by that again...

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

130
4
÷ 2 =
65
2

Let's try dividing by that again...

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

No good. 3 is larger than 2. So we're done reducing.

There you have it! Here's the final answer to 32/1 + 4/8

32
1
+
4
8
=
65
2
