Question

by what number should -16/21 be divided so that the quotient is -4/7 ? ​

Answer 1

Let, the number be x

$\frac{ \frac{ - 16}{21} }{x} = \frac{ - 4}{7} \\ \\ = > \frac{ - 16}{21x} = \frac{ - 4}{7} \\ \\ = > x = \frac{ - 16 \times 7}{ - 4 \times 21} \\ \\ = > x = \frac{4}{3}$

So, the number will be 4/3
