Answer 1

4,3,2,5

Step-by-step explanation:

All zero placed to the right of a decimal point in a number are significant.

1.200 = two significant figures

The zero written to the left of the first non-zero digits in a number are not significant.

0.00340 = three significant figures.

The zero written without digits and after non-zero digits are not significant.

55000 = two significant figures.

The zero between two non-zero digits in a number are significant.

80.080 = five significant figures.
