What is 55/55 + 1/3?

What is 55/55 + 1/3?

This is how you add

55
55
+
1
3

Step 1

Of course, you can't add two fractions if the denominators (bottom numbers) don't match. To get a common denominator, multiply the denominators together. Then we fix the numerators by multiplying each one by their other term's denominator.

Now you multiply 55 by 3, and get 165, then we multiply 55 by 3 and get 165.

55/55 times 3

Do the same for the second term. We multiply 1 by 55, and get 55, then multiply 55 by 3 and get 165.

1/3 times 55

The problem now has new fractions to add:

165
165
+
55
165

Step 2

Since our denominators match, we can add the numerators.

165 + 55 = 220

This yields the answer

220
165

Step 3

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

To find out, we try dividing 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...

Are both the numerator and the denominator evenly divisible by 5? Yes! So we reduce it:

220
165
÷ 5 =
44
33

Let's try dividing by that again...

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

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

Are both the numerator and the denominator evenly divisible by 11? Yes! So we reduce it:

44
33
÷ 11 =
4
3

Let's try dividing by that again...

No good. 11 is larger than 4. So we're done reducing.

There you have it! Here's the final answer to 55/55 + 1/3

55
