What is 3/11 + 1/10?

Here's how we add

Step 1We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator. Now we multiply 3 by 10, and get 30, then we multiply 11 by 10 and get 110. Now for the second term. You multiply 1 by 11, and get 11, then multiply 11 by 10 and get 110. This gives us a new problem that looks like so:

|||||||||||
Step 2Since our denominators match, we can add the numerators. 30 + 11 = 41 That gives us an answer of
|
|||||||||||
Step 3Can 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... Nope. Try the next prime number, 7... Nope. Try the next prime number, 11... Nope. Try the next prime number, 13... Nope. Try the next prime number, 17... Nope. Try the next prime number, 19... Nope. Try the next prime number, 23... Nope. Try the next prime number, 29... Nope. Try the next prime number, 31... Nope. Try the next prime number, 37... Nope. Try the next prime number, 41... Nope. Try the next prime number, 43... No good. 43 is larger than 41. So we're done reducing. Congratulations! Here's your final answer to 3/11 + 1/10
