Let's add

Step 1Our denominators (bottom numbers) don't match, so we can't add yet. Since 1 is evenly divided by 10, we can multiply just one term to get a common denominator. Multiply 91 by 10, and get 910, then we multiply 1 by 10 and get 10. The problem now has new fractions to add:

Step 2Since our denominators match, we can add the numerators. 910 + 4 = 914 This yields the answer

||||||||||||||||||
Step 3The last step is to reduce the fraction if we can. 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... 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 91/1 + 4/10
