Question

by what rational number should-9/11 be multiplied to get 27/-55.
Please give me the answer with process.​

Answer 1

Answer:

let the rational number be 1/x

$- \frac{9}{11} \times \frac{1}{x} = \frac{27}{ - 55}$

$1 \div x = \frac{27}{ - 55} \times \frac{ - 11}{9}$

1/x = -3/5 × -1

therefore 1/x = 3/5

the rational number is 3/5
