Question

If the product of two rational is 13/15 if one on the number is -5/6.find the other rational number

Answer 1

Let the rational number be x

second number = -5/6

product of two number = 13/15

$x \times - \frac{ 5}{6} = \frac{13}{15} \\ transpose \: the \: values \\ x = \frac{13 \times 5}{15 \times 6} \\ x = \frac{13}{18}$

other number = 13/18

Answer 2

Answer:

Step-by-step explanation:

Let other no. Be y

-5/6*y =13/15

Then do cross multiply

=-5x y15=13×6

=-75y=78

Y=78/75

=y=26/25 answer
