Question

The product of two numbers is 5/9.if one of the number is -35/24 find other

Answer 1

Product of two number= 5/9
One of the number= -35/24
Let the other no. be x
A/Q
-35/24x= 5/9
therefore, x= 5/9 / -35/24
=> x = 5/9 * 24/ -35
=> x = -8/21

Answer 2

Let the unknown no be x.
So we can form the equation,

$x * \frac{-35}{24} = \frac{5}{9}$

Now Cross-multiplying,
We get, 

$x = \frac{-5*24}{35*9}$  [ now cancelling the terms as required]

x = $\frac{-8}{21}$
