Step 1Now we need to make our denominators match. 12 goes into 1 evenly, so we only need to multiply one term to get a common denominator. Multiply 12 by 12, and get 144, then we multiply 1 by 12 and get 12. This gives us a new problem that looks like so:
|
|||||||||||||||||||||||||
Step 2Since our denominators match, we can add the numerators. 144 + 8 = 152 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:
Let's try dividing by that again... Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
Let's try dividing by that again... Nope! So now we try the next greatest prime number, 3... Nope! So now we try the next greatest prime number, 5... No good. 5 is larger than 3. So we're done reducing. There you have it! Here's the final answer to 12/1 + 8/12
