Question

Order the following from least to greatest:
6.8 x 106 , 6 x 106 , 6.6 x 10-6 ,6.1 x 10-6

Answer 1

To order the numbers \(6.8 \times 10^6\), \(6 \times 10^6\), \(6.6 \times 10^{-6}\), and \(6.1 \times 10^{-6}\) from least to greatest, we should first convert all of them to a comparable format.

1. **Convert the numbers**:
- \(6.8 \times 10^6 = 6800000\)
- \(6 \times 10^6 = 6000000\)
- \(6.6 \times 10^{-6} = 0.0000066\)
- \(6.1 \times 10^{-6} = 0.0000061\)

2. **Now, order them**:
- \(6.1 \times 10^{-6} = 0.0000061\)
- \(6.6 \times 10^{-6} = 0.0000066\)
- \(6 \times 10^6 = 6000000\)
- \(6.8 \times 10^6 = 6800000\)

Putting it all together, the order from least to greatest is:
\[
6.1 \times 10^{-6}, \; 6.6 \times 10^{-6}, \; 6 \times 10^6, \; 6.8 \times 10^6
\]
