Q. The planet Uranus is about

3 \times 10^9

kilometers from the sun. The dwarf planet Pluto is about

6 \times 10^9

kilometers from the sun. Use these numbers to complete the sentence below. Write your answer in standard form, without using exponents. Uranus is about ____ times as far from the sun as Pluto.

Calculate ratio: Calculate the ratio of the distance of Uranus to the distance of Pluto. $3 \times 10^9 \text{ km} \, (\text{Uranus}) / 6 \times 10^9 \text{ km} \, (\text{Pluto}) = 0.5$
Convert to standard form: Convert the ratio into standard form without exponents. $\newline$ $0.5$ in standard form is $0.5$ , which means Uranus is about $0.5$ times as far from the sun as Pluto.
