We are given the expanded form and we need to write the standard form:
10 + 8x(1/10) + 3 x(1/100) + 9 x (1/1000)
So, that is:
10 + 0.8 + 0.03 + 0.009
= 10.839
Hi there!
To get the answer to this question, let's divide the diameter of the Earth by the diameter of Mercury.

We can change this to

Let's solve for each individual fraction

≈ 0.27

= 10
Now, multiply.
0.27 * 10 = 2.7
That's your answer.
Have an awesome day/night! :)
