Let the number be - x-According to question-x -times -dfrac-15-20- - -dfrac-5-7-Rightarrow x - -dfrac-5 -times 20-7 -times -15-Rightarrow x - -dfrac-22-21-Hence- The other number is -dfrac-22-21-

By what numbers should we multiply $$\dfrac{-15}{20}$$ so that the product may be $$\dfrac{-5}{7}$$ ?

Let the number be $$ x$$

According to question,
$$x \times \dfrac{-15}{20} = \dfrac{-5}{7}$$
$$\Rightarrow x = \dfrac{(-5 )\times 20}{7 \times (-15)}$$
$$\Rightarrow x = \dfrac{22}{21}$$

Hence, The other number is $$\dfrac{22}{21}$$.
