Question

The product of two rational numbers is -11/12.If one of them is 22/9. Find the other.

Answer 1

Let the other number be y

$\frac{22}{9} \times y = \frac{ - 11}{12}$
$y = \frac{ - 11}{12} \times \frac{9}{22} \\ = \frac{ - 9}{2 \times 12}$
$= \frac{ - 3}{8}$

Answer 2

Let the 2 nos. Be x and y
ATQ=x×y=-11÷12
Let the given no.be x
X=22÷9
22÷9×y=-11÷12
y=-11÷12×9÷22
After cancelling the terms
y=-3÷8
