Solve the following exercise:
Solve the following exercise:
To solve this problem, we'll perform the following steps:
Let's apply these steps starting with the first one.
Step 1: Find the Least Common Denominator
The denominators are and . The least common denominator is the smallest number that both denominators divide into evenly. In this case, the LCD is because it is the smallest number that is a multiple of both and .
Step 2: Convert fractions to have the same denominator of
- The fraction needs to be converted to a denominator of . To do this, multiply both the numerator and denominator by :
- The fraction already has the denominator , so it remains unchanged as .
Step 3: Subtract the numerators
Now that the fractions have the same denominator, subtract the numerators:
Therefore, the solution to is .
