Here's how we add
Since our denominators match, we can add the numerators.
4 + 1 = 5
That gives us an answer of
Can this fraction be reduced?
First, we attempt to divide it by 2...
Nope. Try the next prime number, 3...
Nope. Try the next prime number, 5...
Are both the numerator and the denominator evenly divisible by 5? Yes! So we reduce it:
Now, try the same number again.
No good. 5 is larger than 1. So we're done reducing.
Congratulations! Here's your final answer to 4/10 + 1/10
