Answer:
you can't add two fractions if the denominators (bottom numbers) don't match. To get a common denominator, multiply the denominators together. Then we fix the numerators by multiplying each one by their other term's denominator.
Now you multiply 1 by 4, and get 4, then we multiply 6 by 4 and get 24.Since our denominators match, we can add the numerators.
4 + 18 = 22
The sum we get is
22
24
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
22
24
÷ 2 =
11
12
So far so good... let's try to divide by that number again.
No good. So next you try the next prime number, which is 3...
No good. So next you try the next prime number, which is 5...good. So next you try the next prime number, which is 7...
No good. So next you try the next prime number, which is 11...
No good. So next you try the next prime number, which is 13...
No good. 13 is larger than 11. So we're done reducing.
And we're done! Here's the final answer to 1/6 + 3/4 = 11/12
