saturn is 8.867×10^8 miles away from the sun. uranus is 1.787×10^9 miles away from the sun. approximately…

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. The distance of Saturn from the sun is $d_{Saturn}=8.867\times 10^{8}$ miles and the distance of Uranus from the sun is $d_{Uranus}=1.787\times 10^{9}$ miles. The calculation is $\frac{d_{Uranus}}{d_{Saturn}}=\frac{1.787\times 10^{9}}{8.867\times 10^{8}}$.

Step2: Use exponent - division rule

According to the rule $\frac{a\times10^{m}}{b\times10^{n}}=\frac{a}{b}\times10^{m - n}$, we have $\frac{1.787\times 10^{9}}{8.867\times 10^{8}}=\frac{1.787}{8.867}\times10^{9 - 8}$.

Step3: Calculate the fraction and the exponent

$\frac{1.787}{8.867}\approx0.2$ and $10^{9 - 8}=10^{1} = 10$. Then $0.2\times10 = 2$.

Answer:

2 times
