Answer 1

11.35

Explanations:

Given the mathematical operations:

`15.225-3.88`

For each term, we can see that;

15.255 (to thousandth places)

3.88 (to hundredths place)

Taking the difference of the decimal values

`15.225-3.88=11.345`

The final result will be rounded up to the term that has the least decimal place (hundredth place). This shows that the value 11.345 will be converted to 2 decimal places which are equivalent to 4 significant places.

Hence the answer to the correct significant figure is 11.35
