Question

[-65/14] by [13/-7] ​

Answer 1

$\frac{5}{2}$

Step-by-step explanation:

$Given, \: \: [-65/14] by [13/-7] \\ = > \: \: \: \frac{ - 65}{14} \div \frac{13}{ - 7} \\ = > \: \: \: \frac{ - 65}{14} \times \frac{ - 7}{13} \\ = > \: \: \: \frac{ - 5}{2} \times \frac{ - 1}{1} \\ = > \: \: \: \frac{5}{2}$

Answer 2

Answer:

5/2

first we write (13/-7) in standard form

= (13/7)

(13×-1) (-7×-1)

=(-13/7)

now we have (-65/13) × (-13/7)

(-13/7) (7/-13)

the product of two rational numbers = (product of their numerator) ( product of their denominator)

= (-65×14) (7×-13)

on simplifying =-(5×1)/(2×-1)

(-5)/(-2)

=(5/2)
