The correct Answer is:
To solve the expression \( \frac{2}{5} \times 5\left(1\frac{1}{5}\right) \), we will follow these steps: ### Step 1: Convert the mixed number to an improper fraction The mixed number \( 1\frac{1}{5} \) can be converted to an improper fraction. To convert \( 1\frac{1}{5} \): - Multiply the whole number (1) by the denominator (5): \( 1 \times 5 = 5 \). - Add the numerator (1): \( 5 + 1 = 6 \). - Place this over the denominator (5): \( \frac{6}{5} \). So, \( 1\frac{1}{5} = \frac{6}{5} \). ### Step 2: Rewrite the expression Now, we rewrite the original expression using the improper fraction: \[ \frac{2}{5} \times 5 \times \frac{6}{5} \] ### Step 3: Simplify the expression We can simplify the expression step by step. First, we can multiply \( 5 \) and \( \frac{6}{5} \): \[ 5 \times \frac{6}{5} = \frac{5 \times 6}{5} = \frac{30}{5} = 6 \] Now, we substitute this back into our expression: \[ \frac{2}{5} \times 6 \] ### Step 4: Multiply the fractions Now we multiply \( \frac{2}{5} \) by \( 6 \): \[ \frac{2}{5} \times 6 = \frac{2 \times 6}{5} = \frac{12}{5} \] ### Step 5: Final answer Thus, the final answer is: \[ \frac{12}{5} \]
