Hi!
I can help you with joy!
Remember that
* Zeros in the beginning of decimals are not significant figures.
For example, 0.021 has only 2 significant figures: 2 and 1.
* Zeros in the end of decimals are significant.
For example, 2.100 has 4 significant digits.
Now, let's round 0.02852 to 3 significant digits.
Right now it has 4.
Recall the Rounding Rules:
- If the number you are rounding is followed by a number less than 5, you round down.
- If the number you are rounding is followed by a number greater than or equal to 5, you round up.

![\text{0.02852 Round down: 0.0285 (Answer)}](https://img.qammunity.org/2023/formulas/mathematics/college/ysmg304pbr5ef74vjnz3dpfzcupjza0vk5.png)
Hope it helps!
Enjoy your day!
