Question

sum of two rational numbers is -3/7 if one of them is 2/3.find the other number
​

Answer 1

Step-by-step explanation:

let the other no. be x

.

. . Accordin to ques,

x= -23/21

x= -23/21x + 2/3 = -3/7

x= -23/21x + 2/3 = -3/7x = -3/7 - 2/3

x = -9-14/21

x = -23/21

hope it helps!!!

Answer 2

Step-by-step explanation:

Given:-

Sum of two rational numbers is -3/7 if one of them is 2/3.

To find:-

Find the other number ?

Solution:-

Given that

Let the other rational number be X

One of the rational numbers = 2/3

Sum of the rational numbers = (2/3) + X

According to the given problem

Sum of the two rational numbers = -3/7

=>(2/3) + X = (-3/7)

=>X = (-3/7) -(2/3)

LCM of 7 and 3 = 21

=>X = [(-3×3)+(-2×7)]/21

=>X =[(-9)+(-14)]/21

=>X = -23/21

Therefore, X = -23/21

Answer:-

The other rational number for the given problem is -23/21

Check:-

Sum of the two rationals

=>(2/3)+(-23/21)

LCM of 3 and 21 = 21

=>[(2×7)+(-23×1)]/21

=>(14-23)/21

=>-9/21

=>(-3×3)/(3×7)

=>-3/7

Verified the given relation.
