This is how you add
Our denominators (bottom numbers) don't match, so we can't add yet.
Since 4 is evenly divided by 8, we can multiply just one term to get a common denominator.
Multiply 2 by 2, and get 4, then we multiply 4 by 2 and get 8.
So now our fractions look like this:
Since our denominators match, we can add the numerators.
2 + 4 = 6
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:
Now, try the same number again.
Nope. Try the next prime number, 3...
Nope. Try the next prime number, 5...
No good. 5 is larger than 3. So we're done reducing.
Congratulations! Here's your final answer to 2/8 + 2/4
