Answer:0.83


(83)/(100)

Explanation:

Our denominators (bottom numbers) don't match, so we can't add yet.

12 goes into 3 evenly, so we only need to multiply one term to get a common denominator.

Multiply 2 by 4, and get 8, then we multiply 3 by 4 and get 12.

Since our denominators match, we can add the numerators.

2 + 8 = 10


\frac{10} {12}

Now, do we need to simplify this fraction?

First, we attempt to divide it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

10

12

รท 2 =

5

6

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! You've solved the problem.
