Question

if sum of two rational number is -4 if one of them is -11/5 find the other​

Answer 1

Answer:

Let the rational number be x/y

Sun of two rational number be

X/y + (-11/5) = - 4

X/y - 11/5 = - 4

X/y = - 4 +11/5

On taking lcm on rhs side

X/y = - 20+11/5

X/y = - 9/5

Answer 2

Step-by-step explanation:

the sum of two rational number =-4

one of them =-11/5

let the other number be x

A/C

-11/5 + x = -4

x= -4+11/5

x=-20+11/5

x=-9/5

so, the answer is -9/5

-11/5+-9/5 = -4

-11+(-9)/5 = -4

-20/5=-4

-4=-4

LHS=RHS
