The equation given in the question is
- 3 1/3 = 1/2g
- 10/3 = 1/2g
- (10 * 2g) = 1 * 3
- 20g = 3
- g = 3/20
g = - (3/20)
So
the value of g that has been deduced is -(3/20). This is the easiest
procedure to get to the solution of the question gives. Based on the
above procedure, similar problems can be easily solved without any error
or issue. I hope this solution has helped you.
