Question

The sum of two rational numbers is -81.If one of the numbers is -13/7 find the other number.

Answer 1

Step-by-step explanation:

Let the first rational number be'x'

the other number is(-13/7)

x+(-13/7)=(-81)

x-13)/7=(-81)

x=(-81)+13/7

x=(-567+13)/7

x=(-554)/7

Answer 2

The other value is "79.14". Further explanation is given below.

Step-by-step explanation:

Let the first number be "x".

The second number is "$\frac{-13}{7}$".

The sum is "-81".

Now,

first number+second umber = -81

On putting the values, we get

x+($\frac{-13}{7}$) = -81

x-$\frac{13}{7}$ = -81

x = -81+$\frac{13}{7}$

x = $\frac{-567+13}{7}$

x = $\frac{-554}{7}$

x = 79.14
