Question

what should be added to twice rational number -7/3to get 3/7​

Answer 1

Given: Two rational numbers -7/3 and 3/7​.

To find: what should be added to twice rational number -7/3 to get 3/7​

Solution:

• Let the number added be a.

• According to the question, we have:

                 2(-7/3) + a = 3/7

                 -14/3 + a = 3/7

                 a = 3/7 + 14/3

                 a = 9 + 98 / 21

                 a = 107 / 21

Answer:

           So the number that must be added to twice rational number -7/3 to get 3/7​ is 107 / 21.

Answer 2

Answer:

The Answer is:- 107 / 21

Step-by-step explanation:

Given: Two rational numbers -7/3 and 3/7​.

To find: what should be added to twice rational number -7/3 to get 3/7​

Solution:

Let the number added be a.

According to the question, we have:

 2(-7/3) + a = 3/7

-14/3 + a = 3/7

a = 3/7 + 14/3

=9 + 98 / 21

a = 107 / 21

So the number that must be added to twice rational number -7/3 to get 3/7​ is 107 / 21.
