First convert each fraction to an improper fraction by multiplying the denominator by the whole number and then adding the numerator. Place the result over the original denominator.

The problem now looks like this:

Only fractions with the same denominator can be added or subtracted. The least common denominator (LCD) must be determined. One way to do this is by writing the multiples for each denominator. The first one that is the same for both denominators is the LCD.

The LCD is

Now multiply each fraction by an

Simplify.

The mixed fraction is
