Order the following numbers written in scientific notation from greatest to least: 3.9 × 105, 6.1 × 103, 9.3 × 105, 1.6 × 103 A. 9.3 × 105, 3.9 × 105, 6.1 × 103, 1.6 × 103 B. 1.6 × 103, 6.1 × 103, 9.3 × 105, 3.9 × 105, C. 3.9 × 105, 9.3 × 105, 1.6 × 103, 6.1 × 103,

Answer 1

The numbers are:

3.9 × 105 = 409.5

6.1 ×103 = 628.3

9.3 × 105 = 976.5
