Question

The diameter of Mercury is approximately 4.9×10^3 kilometers. The diameter of Earth is approximately 1.3×10^4 kilometers. About how many times greater is the diameter of Earth than the diameter of Mercury? 2.7 27 270 2700

Answer 1

`\text {Number of times = } (1.3 * 10^4)/(4.9 * 10^3 )`


`\text {Number of times = } (1.3)/(4.9) * 10^(4-3)`


`\text {Number of times = } 0.27 * 10`


`\text {Number of times = } 2.7`
