The correct Answer is:
To evaluate the expression \( 7\frac{9}{5} - 2\frac{2}{5} - 1\frac{4}{5} \), we will follow these steps: ### Step 1: Convert mixed numbers to improper fractions First, we need to convert each mixed number into an improper fraction. 1. **Convert \( 7\frac{9}{5} \)**: \[ 7\frac{9}{5} = \frac{7 \times 5 + 9}{5} = \frac{35 + 9}{5} = \frac{44}{5} \] 2. **Convert \( 2\frac{2}{5} \)**: \[ 2\frac{2}{5} = \frac{2 \times 5 + 2}{5} = \frac{10 + 2}{5} = \frac{12}{5} \] 3. **Convert \( 1\frac{4}{5} \)**: \[ 1\frac{4}{5} = \frac{1 \times 5 + 4}{5} = \frac{5 + 4}{5} = \frac{9}{5} \] ### Step 2: Rewrite the expression Now we can rewrite the original expression using the improper fractions: \[ \frac{44}{5} - \frac{12}{5} - \frac{9}{5} \] ### Step 3: Combine the fractions Since all fractions have the same denominator, we can combine them directly: \[ \frac{44 - 12 - 9}{5} \] ### Step 4: Perform the subtraction in the numerator Now, we will perform the subtraction in the numerator: \[ 44 - 12 = 32 \] \[ 32 - 9 = 23 \] ### Step 5: Write the final result Now we can write the final result: \[ \frac{23}{5} \] ### Final Answer: The evaluated expression is \( \frac{23}{5} \). ---
