What is 91/1 + 4/6?

What is 91/1 + 4/6?

Here's how we add

91
1
+
4
6

Step 1

Now we need to make our denominators match.

Since 1 is evenly divided by 6, we can multiply just one term to get a common denominator.

Multiply 91 by 6, and get 546, then we multiply 1 by 6 and get 6.

91/1 times 6

The problem now has new fractions to add:

546
6
+
4
6

Step 2

Since our denominators match, we can add the numerators.

546 + 4 = 550

The sum we get is

550
6

Step 3

The last step is to reduce the fraction if we can.

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:

550
6
÷ 2 =
275
3

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...

No good. 5 is larger than 3. So we're done reducing.

There you have it! Here's the final answer to 91/1 + 4/6

91
1
+
4
6
=
275
