What is 12/1 + 2/10?

Here's how we add

||||||||||||||||||
Step 1Our denominators (bottom numbers) don't match, so we can't add yet. 10 goes into 1 evenly, so we only need to multiply one term to get a common denominator. Multiply 12 by 10, and get 120, then we multiply 1 by 10 and get 10. This gives us a new problem that looks like so:
|
||||||||||||||||||
Step 2Since our denominators match, we can add the numerators. 120 + 2 = 122 That gives us an answer of
|
||||||||||||||||||
Step 3Can this fraction be reduced? First, we attempt to divide 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... Nope. Try the next prime number, 7... No good. 7 is larger than 5. So we're done reducing. Congratulations! Here's your final answer to 12/1 + 2/10
