The correct Answer is:
To solve the equation \( \frac{1}{y} + \frac{1}{2y} + \frac{1}{3y} \), we will follow these steps: ### Step 1: Find a common denominator The denominators are \( y \), \( 2y \), and \( 3y \). The least common multiple (LCM) of these denominators is \( 6y \). ### Step 2: Rewrite each fraction with the common denominator We will rewrite each term with the common denominator \( 6y \): - \( \frac{1}{y} = \frac{6}{6y} \) - \( \frac{1}{2y} = \frac{3}{6y} \) - \( \frac{1}{3y} = \frac{2}{6y} \) ### Step 3: Combine the fractions Now we can combine the fractions: \[ \frac{6}{6y} + \frac{3}{6y} + \frac{2}{6y} = \frac{6 + 3 + 2}{6y} = \frac{11}{6y} \] ### Step 4: Write the final answer Thus, the value of \( \frac{1}{y} + \frac{1}{2y} + \frac{1}{3y} \) is: \[ \frac{11}{6y} \]
