Question

The mass of one grain of sand is 1.1×10^–2 gram.
How is 1.1×10^–2 written in standard notation?
Responses
A 0.0110.011
B 0.110.11
C 0.00110.0011
D 110

Answer 1

To convert \(1.1 \times 10^{-2}\) to standard notation, you move the decimal point two places to the left (since it's a negative exponent).

Starting with \(1.1\), moving the decimal two places to the left gives:

1. Move from \(1.1\) to \(0.1\) (first move).
2. Move from \(0.1\) to \(0.011\) (second move).

Therefore, \(1.1 \times 10^{-2} = 0.011\).

So, the correct answer is:

**A \(0.011\)**.
