What is 19/100 + 6/10?

What is 19/100 + 6/10?

This is how you add

19
100
 +
6
10

Step 1

Now we need to make our denominators match.

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

Multiply 6 by 10, and get 60, then we multiply 10 by 10 and get 100.

6/10 times 10

We now have a new problem, that looks like this:

19
100
 +
60
100

Step 2

Since our denominators match, we can add the numerators.

19 + 60 = 79

That gives us the sum, which is

79
100

Step 3

Now, do we need to simplify this fraction?

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...

Nope! So now we try the next greatest prime number, 13...

Nope! So now we try the next greatest prime number, 17...

Nope! So now we try the next greatest prime number, 19...

Nope! So now we try the next greatest prime number, 23...

Nope! So now we try the next greatest prime number, 29...

Nope! So now we try the next greatest prime number, 31...

Nope! So now we try the next greatest prime number, 37...

Nope! So now we try the next greatest prime number, 41...

Nope! So now we try the next greatest prime number, 43...

Nope! So now we try the next greatest prime number, 47...

Nope! So now we try the next greatest prime number, 53...

Nope! So now we try the next greatest prime number, 59...

Nope! So now we try the next greatest prime number, 61...

Nope! So now we try the next greatest prime number, 67...

Nope! So now we try the next greatest prime number, 71...

Nope! So now we try the next greatest prime number, 73...

Nope! So now we try the next greatest prime number, 79...

Nope! So now we try the next greatest prime number, 83...

No good. 83 is larger than 79. So we're done reducing.

There you have it! Here's the final answer to 19/100 + 6/10
