Question

The sum of two rational numbers is -5/2. If one is -7/3, find the other.
Please give me the explanation of this sum as I am stuck with the answer... ​

Answer 1

Answer:

It is given that

Sum of two rational numbers =

12

−7

One of the rational number =

24

13

Other rational number =x

24

13

+x=

12

−7

x=

12

−7

−

24

13

LCM of 12 and 24 is 24

=

12×2

−7×2

−

24

13

By further calculation

=

24

−14

−

24

13

So we get

=

24

−14−13

=

24

−27

=

8

−9

Answer 2

Answer:

1/6

Step-by-step explanation:

given that,

sum of the numbers= -5/2

one of them = -7/3

other number = ?

so,

let others no. be x then,

-7/3 + x= -5/2

x= -5/2-(-7/3)

x= -5/2+7/3

now we will take the LCM of 2 and 3

the LCM of 2 and 3 =6

then x= -15+14/6

x= 1/6

so other no. is 1/6.
