Answer 2

Step 1

We can't add two fractions with different denominators (the bottom number). So you need to get a common denominator - both bottom numbers need to match. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 3 by 12, and get 36, then we multiply 8 by 12 and get 96.

Do the same for the second term. We multiply 5 by 8, and get 40, then multiply 8 by 12 and get 96.

So now our fractions look like this:

3696+4096

Step 2

Since our denominators match, we can add the numerators.

36 + 40 = 76

Now we have an answer.

7696

Here's how to add

38+512

So now our fractions look like this:

3696+4096

36 + 40 = 76

Now we have an answer.

7696

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

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:

7696÷ 2 =3848

Now, try the same number again.

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

3848÷ 2 =1924
