By what number should we multiply `(-15)/(28)` so that the product may be `(-5)/7?`

Explanation

To find the number by which we should multiply \(-\frac{15}{28}\) so that the product equals \(-\frac{5}{7}\), we can set up the equation as follows:

Let the unknown number be \(y\).

The equation can be written as:
\[ -\frac{15}{28} \times y = -\frac{5}{7} \]
