What is 32/1 + 2/10?

What is 32/1 + 2/10?

This is how we add

32
1
+
2
10

Step 1

Now we need to make our denominators match.

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

Multiply 32 by 10, and get 320, then we multiply 1 by 10 and get 10.

32/1 times 10

This gives us a new problem that looks like so:

320
10
+
2
10

Step 2

Since our denominators match, we can add the numerators.

320 + 2 = 322

So what's the answer so far?

322
10

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:

322
10
÷ 2 =
161
5

Let's try dividing by that again...

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

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

Nope! So now we try the next greatest prime number, 7...

No good. 7 is larger than 5. So we're done reducing.

There you have it! Here's the final answer to 32/1 + 2/10

32
1
+
2
10
=
161
5
