Question

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

Answer 1

Answer:

The answer is as follows:-

Step-by-step explanation:

Let the required number be x.

x+(-14/3) =3/7.

x = 14/3 + 3/7.

x = [(14 x 7) + ((3 x 3)]/(3 x 7)

x = (98+9)/21

x = 107/21.

Answer 2

Answer:

Step-by-step explanation:

LET THE UNKNOWN NUMBER BE X

GIVEN :

X+2*(-7/3)  = 3/7

X-14/3 = 3/7

X = 3/7+14/3

X = (3*3)+(7*14)/7*3

X = (9+98)/21

X = 107/21.

THEREFORE THE UNKNOWN NUMBER IS 107/21.
