Question

The density of Venus, compared to Earth having a density of 1,

is 0.943. The density of Mercury is 0.983, compared to the
density of Earth. Which planet has a greater density, Venus or
Mercury?

Answer 1

Mercury

Explanation:

We'll translate this into ratios.

First, V:E = 0.943:1

Then, M:E = 0.983:1

We already have their density in terms earth's density. They are in the same unit. So, we can compare them directly, with greater ratio means greater density. It's clear that Mercury has the greater density.
