Question

The diameter of Mercury is approximately 4.9×103 kilometers. The diameter of Earth is approximately 1.3×104 kilometers. About how many times greater is the diameter of Earth than the diameter of Mercury? 2.7 27 270 2700

Answer 1

Hi there!

To get the answer to this question, let's divide the diameter of the Earth by the diameter of Mercury.

$\frac{1.3*10^4}{4.9*10^3}$

We can change this to

$\frac{1.3}{4.9}*\frac{10^4}{10^3}$

Let's solve for each individual fraction

$\frac{1.3}{4.9}$ ≈ 0.27

$\frac{10^4}{10^3}$ = 10

Now, multiply.

0.27 * 10 = 2.7

That's your answer.

Have an awesome day/night! :)
