Answer

Explanation:

Step1: Set up the division

We want to find out how many times farther Uranus is from the Sun than Saturn. So we divide the distance of Uranus from the Sun by the distance of Saturn from the Sun. Let $d_U = 1.787\times10^{9}$ be the distance of Uranus from the Sun and $d_S=8.867\times 10^{8}$ be the distance of Saturn from the Sun. The calculation is $\frac{d_U}{d_S}=\frac{1.787\times 10^{9}}{8.867\times 10^{8}}$.

Step2: Use exponent - division rule

According to the rule $\frac{a\times10^{m}}{b\times10^{n}}=\frac{a}{b}\times10^{m - n}$, we have $\frac{1.787}{8.867}\times10^{9 - 8}$. First, $\frac{1.787}{8.867}\approx0.2$, and $10^{9 - 8}=10^{1} = 10$. Then $0.2\times10 = 2$.

Answer:

2 times
