Question

the sum of two rational number is -6/11. If onebif the number is -66/77, find the other.​

Answer 1

Answer:

24/77

Step-by-step explanation:

let the rational number be x

$\frac{ - 66}{77} + x = - \frac{6}{11} \\ x = - \frac{6}{11} + \frac{66}{77} \\ x = \frac{ - 42 + 66}{77} \\ x = \frac{24}{77}$

verification

$- \frac{66}{77} + \frac{24}{77} \\ = \frac{ - 66 + 24}{77} \\ = - \frac{42}{77} \\ = - \frac{6}{11}$

hope you get your answer

Answer 2

Answer:

Given,

sum of two rational numbers=-6/11

one of the rational number=-66/77

other number=?

As per sum,

-66/77+x=-6/11

x=-6/11-(-66/77)

LCM OF 11 AND 77 IS 77

x= -6*7/11*7-(-66/77)

x= -42/77-(-66/77)

x= -42/77+(66/77)

x= -24/77

CHECK: -66/77+-24/77=-42/77=-6/11
