Step 1

Since our denominators match, we can add the numerators.

1 + 10 = 11

11
11

Step 2

Can this fraction be reduced?

First, we attempt to divide it by 2...

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...

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

11
11
÷ 11 =
1
1

Let's try dividing by that again...

No good. 11 is larger than 1. So we're done reducing.
