What is 91/1 + 3/10?

What is 91/1 + 3/10?

Here's how to add

91
1
+
3
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 91 by 10, and get 910, then we multiply 1 by 10 and get 10.

91/1 times 10

This gives us a new problem that looks like so:

910
10
+
3
10

Step 2

Since our denominators match, we can add the numerators.

910 + 3 = 913

That gives us an answer of

913
10

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...

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

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

Nope! So now we try the next greatest prime number, 11...

No good. 11 is larger than 10. So we're done reducing.

There you have it! Here's the final answer to 91/1 + 3/10

91
1
+
3
10
=
913
10
