Find the Least Common Denominator (LCD). This is the smallest number that 8 and 16 can be divided into without remainder:
Rewrite the fractions in terms of the LCD. For the first term, you need to multiply the denominator (8) by 2 to get 16. If you multiply the denominator by 2, you also need to multiply the numerator by 2 so that the fraction does not change.
For the second term, you don't have to change anything since the denominator is already the LCD.
So now the expression becomes this:
Simplify the first term:
Now that the denominators of the 2 terms are equal, you can add them up. To do this, add the numerators and keep the denominator the same:
This fraction can be reduced. Both numerator and denominator can be divided by 4. This gives you your final answer:
