What is 91/1 + 6/10?

What is 91/1 + 6/10?

This is how we add

91
1
+
6
10

Step 1

Now we need to make our denominators match.

Since 1 is evenly divided by 10, we can multiply just 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

So now our fractions look like this:

910
10
+
6
10

Step 2

Since our denominators match, we can add the numerators.

910 + 6 = 916

Now we have an answer.

916
10

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

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

916
10
÷ 2 =
458
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 91/1 + 6/10

91
1
+
6
10
=
458
5
