The Product of Two Numbers is -4/9. If One of Them is -2/27, Find the Other. - Mathematics

The product of two numbers is $\frac{- 4}{9}$ . If one of them is $\frac{- 2}{27}$ , find the other.

Sum

∴ The product of two numbers is = $- \frac{4}{9}$

And, one of them is = $\frac{- 2}{27}$

∴The other number = $- \frac{4}{9} \div (\frac{- 2}{27})$

= $- \frac{4}{9} \times \frac{27}{- 2}$

= $\frac{2 \times 3}{1 \times 1} = 6$
