Question

The sum of two rational numbers is (-4).If one of them is -11/5,find the other​

Answer 1

Answer:

The other number is -9/5

Step-by-step explanation:

Step 1:

Let the other number be x

Therefore the equation will be:

-11/5 + x = -4

Step 2:

take l.c.m of all(5)

-11/5 + x×5/5 =-4

Step 3:

-11/5 + 5x/5 =-4

Step 4:

-11/5 + 5x/5 + 4=0

Step 5:

-11/5 + 5x/5 + 4×5/5=0

-11+5x/5 +20/5 =0

Step 6:

5 will go on right hand side and it will multiply by 0,that is 0×5=0

Step 7:

-11 + 5x +20=0

9+5x=0

Step 8:

5x=-9

x=-9/5

VERIFICATION:-

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

-20/5 = (-4)

-4=-4
