To find the LCD, we calculate the LCM of all denominators: [12, 12, 12].
The LCD is 12.
Step 2: Convert each fraction to an equivalent fraction with the LCD
Fraction 1: \(\frac{9}{12}\) becomes \(\frac{9}{12}\).
Fraction 2: \(\frac{11}{12}\) becomes \(\frac{11}{12}\).
Fraction 3: \(\frac{7}{12}\) becomes \(\frac{7}{12}\).
All fractions are converted to have 12 as the denominator.
Step 3: Sum the numerators
The sum of the converted numerators is 27.
Step 4: Simplify the resulting fraction
The GCD of 27 and 12 is 3.
The fraction \(\frac{27}{12}\) simplifies to \(\frac{9}{4}\).
Final Answer:
The sum of the given fractions is approximately 2.25 when rounded to 2 decimal places.
