Explanation:
Here are the three rules you need.
- All
color (red)("non-zero digits") are significant. color(red)("Trailing zeroes in the decimal portion") of a number are significant.- In multiplication and division,
color(red)("you round the answer to have"
color(red)("the same number of significant digits as the number with the")
color(red)("fewest significant figures") .
You used a period as a decimal separator in 4.0, so I assume you are using the comma as a thousands separator in 1,632.
The answer can have only two significant figures.
∴
