Question

The product of two rational numbers is -8/9 ,If one of the number is -17/6, then find the other?

Answer 1

$let \: the \: unknown \: number \: be \: \: p \\ \\ then \\ p( \frac{ - 8}{9} ) = \frac{ - 17}{6} \\ \\ p = \frac{ - 17}{6} \div \frac{ - 8}{9} \\ \\ p = \frac{ - 17}{6} \times \frac{9}{ - 8} \\ \\ p = \frac{17 \times 3}{2 \times 8} = \frac{51}{16} = 3\frac{3}{16}$
