Answer 1

no if the zero after the decimal doesnt have a number other than zero on either side then its insignificant (sigfigs/significant figures)

Answer 2

No, the doctor did not make any mistake.

Explanation:

George was weighed at the doctors office. It read 67.20 pounds.

The doctor wrote 67.2 pounds on scale George's chart.

No, the doctor did not make any mistake as 67.20 and 67.2 are same.

If there is a 0 after decimal and no number after 0, then it has no significance.

Like 3.00 , 2.50 , 4.32000

In these numbers, 0 have no significance.

But if there is a number before 0, then it has values. Like 6.02 , 3.002 , 4.305
