### Example Question #3 : How To Add Fractions

**Possible Answers:**

**Correct answer:**

When adding fractions, both denominators must be the same. A quick and easy way to do this is to multiply the numerator and the denominator of each fraction by the other fraction's denominator:

and

The is multiplied by 6 on both ends because the denominator of is 6. Likewise, is multiplied by 3 on both ends because the denominator of is 3. The problem should now look like this:

Remember to reduce. 15 and 18 are both divisible by 3.

Your answer is .

### Example Question #4 : How To Add Fractions

Add the following fractions and simplify, if possible.

**Possible Answers:**

**Correct answer:**

In order to add fractions with different denominators, first find a common denominator of the fractions by finding the least common multiple. The least common multiple of these denominators is:

and .

Because already has the required denominator, nothing needs to be done to .

Since the in needs to be multiplied by in order to get as the deonominator, multiply the numberator of by .

The "new" addition problem is now: .

The answer to this question is therefore .

Because and do not have a common factor, the answer cannot be simplified.
