Question

The sum of two rational numbers is 18/-25. If one of number is-7/10 find the other number.

Answer 1

Given:

Sum of two rational numbers is 18/-25

One of number is -7/10

To Find:

Other number

Solution:

Let other number be x

ATQ

Sum of both number is 18/-25

So

x + (-7/10) = 18/-25

x = -18/25 + 7/10

Taking LCM

x = (-36 + 35)/50

x = -1/50

Hence, other rational number is -1/50.

Answer 2

Answer:

-1/50

Step-by-step explanation:

sum of two numbers=18/-25

x+y=18/-25

given

x=-7/10

(-7/10)+y=18/-25

y=-(18/25)+(7/10)

y=(-18×10+7×25)÷250

y=(-180+175)÷250

y=-5/250

y=-1/50

verify

x+y

(-7/10)+(-1/50)

(-7×5-1)/50

(-35-1)/50

-36/50

-18/25
