Question

The product of two rational numbers is 15.if one of the number is -25/13,find the other

Answer 1

Answer:

$x = \frac{ - 39}{5}$

Step-by-step explanation:

one of the number. = -25/13

let the other number be x

product = 15

$\frac{ - 25}{13} \times x = 15 \\ \\ x = \frac{15 \times 13}{ - 25} \\ \\ x = \frac{3 \times 13}{ - 5} \\ \\ x = \frac{ - 39}{5}$

Answer 2

Answer:

-39/5

Step-by-step explanation:

x*y = 15

x = -25/13

-25/13 *y = 15

y = 15/ -25/13

= 15* -13/25

= 3* -13/5

= -39/5
