Question

what should be added to twice the rational number -8/3 to get 3/7​

Answer 1

Answer:

Step-by-step explanation:

Let the number that is to be added be x

As per the question,

x + 2 * (-7/3) = 3/7

x – 14/3 = 3/7

(3x – 14)/ 3 = 3 / 7

3x – 14 = 9 / 7

7 (3x – 14) = 9

21x – 98 = 9

21 x = 9 + 98

21 x = 107

x = 107/21.

Answer 2

Answer:

5.76

Step-by-step explanation:

twice of the rational number -8/3 = 2 * -8/3 = -16/3

According to the question

( let's take the answer as X )

then X + (-16/3) = 3/7

X=3/7+16/3

=3*3/7*3+16*7/3*7

=9/21+112/21

X = 121/21 = 5.76

5.76 is your answer

hope you have understood this question
