This is how we add
Since our denominators match, we can add the numerators.
2 + 2 = 4
So the answer is:
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:
Let's try dividing by that again...
Nope! So now we try the next greatest prime number, 3...
No good. 3 is larger than 2. So we're done reducing.
There you have it! Here's the final answer to 2/10 + 2/10
