The number to be multiplied is \frac{343}{64}.

Step-by-step explanation:

Let the number to be multiplied be x.

The expression is:

(-\frac{4}{7})^{2}\times x=(\frac{49}{16})^{-2}\\

Compute the value of x as follows:

(-\frac{4}{7})^{2}\times x=(\frac{49}{16})^{-2}\\

(-\frac{4}{7})^{2}\times x=((\frac{7}{4}))^{2})^{-2}\\

(\frac{4}{7})^{2}\times x=(\frac{7}{4})\\

x=\frac{7}{4}\times (\frac{7}{4})^{2}

x=(\frac{7}{4})^{3}

x=\frac{343}{64}

Thus, the number to be multiplied is \frac{343}{64}.
