Answer 2

✧ SOLUTION ↓

________________________________

⚘ Product of 2 rational numbers = $\dfrac{-12}{13}$

⚘ One number = $\dfrac{8}{15}$

⚘ Other number = ?

________________________________

➠ Let the other number be x, then

________________________________

➠ $\dfrac{8}{15} \times x = \dfrac{-12}{13}$

➠ x = $\dfrac{-12}{13} \div \dfrac{8}{15}$

➠ x = $\dfrac{-12}{13} \times \dfrac{15}{8}$

➠ x = $\cancel\dfrac{-12 \times 15}{13 \times 8}$

➠ x = $\dfrac{-3 \times 15}{13 \times 2}$

➠ x = $\dfrac{-45}{26}$ (Ans)

________________________________

➠ Therefore, the other number is $\dfrac{-45}{26}$.
