To solve the expression \((-4) \times \left(\frac{7}{5}\right) \times \left(-\frac{3}{4}\right) \div \left(\frac{7}{15}\right)\), follow these steps:
Step 1: Simplifying the Division
First, we can rewrite the division by a fraction as multiplication by its reciprocal: \[ \div \left(\frac{7}{15}\right) = \times \left(\frac{15}{7}\right) \] So the expression becomes: \[ (-4) \times \left(\frac{7}{5}\right) \times \left(-\frac{3}{4}\right) \times \left(\frac{15}{7}\right) \]
Step 2: Rearranging the Multiplication
We can group the terms together: \[ (-4) \times \left(-\frac{3}{4}\right) \times \left(\frac{7}{5}\right) \times \left(\frac{15}{7}\right) \]
Step 3: Calculate the Products Step by Step
Part 1: Multiply the Negative Numbers
\[ (-4) \times \left(-\frac{3}{4}\right) = \frac{4 \times 3}{4} = 3 \]
Part 2: Include Remaining Terms
Now we have: \[ 3 \times \left(\frac{7}{5}\right) \times \left(\frac{15}{7}\right) \]
Step 4: Simplify Further
Now, multiply these fractions: \[ 3 \times \left(\frac{7 \times 15}{5 \times 7}\right) \] Here, the \(7\) in the numerator and denominator cancel out: \[ = 3 \times \left(\frac{15}{5}\right) = 3 \times 3 = 9 \]
Conclusion
The final answer is \(9\).
Thus, the correct response is: 9
