Solve the following exercise:
To solve the problem of subtracting the fraction from , follow these steps:
Step 1: Identify the least common multiple (LCM) of the denominators 5 and 10.
The LCM of 5 and 10 is 10.
Step 2: Convert each fraction to an equivalent fraction with the common denominator of 10.
- The fraction can be converted to have a denominator of 10 by multiplying both the numerator and the denominator by 2. Thus, .
- The fraction already has the denominator of 10, so it remains .
Step 3: Subtract the second fraction from the first.
Subtract the numerators while keeping the common denominator: .
Step 4: Simplify the resulting fraction.
The fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2: .
Therefore, the solution to the problem is , which corresponds to choice number 2.
