Question #fcd25

Answer 1

Three.

Explanation:

When counting the number of significant figures in a decimal number, you start counting from the right of the decimal point.

`cancel0color(red)(.00203)`

Counting from left to right from the decimal point , there are 5 digits.

However, the zeroes before any natural number is not counted as a significant figure.

`cancel(0.00)color(red)(203)`

Thus, there are `color(red)3` significant figures ie. 203.

Note: any other numbers added to the right of `0.00203` is also counted as a significant number.

eg. `0.002031` has 4 significant figures.
eg. `0.002030` has 4 significant figures.
