Answer 1

Answer:

Let the unknown number be x

Now,

x/-99/65=13/11

=x=13/11*99/-65(now 99 divided by 11&65 divided by 13)

=x=-9/5

therefore -99/65 should be divided by 9/5 to get 13/11

Answer 2

Answer:

let the no. by which -99/65 is divided be x.

(-99/65)/x = 13/11

x= 13/11 × -99/65

x= -9/5
