Answer:
416 (3 s.f.)
Step-by-step explanation:
To multiply decimals, begin by multiplying the numbers as if there is <u>no decimal</u>:
Count the number of digits <u>after</u> the decimal point in each factor:
- 128.5 → 1 digit after the decimal point.
- 3.24 → 2 digits after the decimal point.
Therefore, there is a total of 3 digits after the decimal points.
Put the same number of digits after the decimal point in the product.
Therefore, the solution is to the multiplication is:
The factor with the <u>fewest signification figures</u> is 3.24.
This number has 3 significant figures.
Therefore, the solution to 3 significant figures is:
