the product of two rational number is -8 by nine .if one of the number is -4 by 15. find the other number

*x*

$firstnumber=-\frac{4}{15}\phantom{\rule{0ex}{0ex}}product=-\frac{8}{9}\phantom{\rule{0ex}{0ex}}now,-\frac{4}{15}\times x=-\frac{8}{9}\phantom{\rule{0ex}{0ex}}\Rightarrow x=-\frac{8}{9}\xf7-\frac{4}{15}=-\frac{8}{9}\times \left(-\frac{15}{4}\right)=\frac{120}{36}=\frac{10}{3}$
