Question

Approximate 0.0032876 to 3 significant figure​

Answer 1

0.00329

Explanation:

The leading zero's are not significant, only there for place value.

The significant digits are 32876 ← 5 significant figures

which rounds to 329 ← 3 significant figures

0.0032876 ≈ 0.00329

Answer 2

0.00329

This is rounded to three significant figures.

The zeros before 32876 will not count as significant since they are before the non-zero numbers.
