Question

the volume of the moon is about 2.18 × 10^10 cubic kilometers. the volume of earth is about 1.09 × 10^12 cubic kilometers. the number of moons that can fit inside earth can be found by dividing earths volume by the moons volume. about how many moons can fit inside earth? 200 50 100 500

Explanation:

Step1: Set up the division

We need to calculate $\frac{1.09\times 10^{12}}{2.18\times 10^{10}}$.

Step2: Divide the coefficients and subtract exponents

First, divide the coefficients: $\frac{1.09}{2.18}=0.5$. Then, subtract the exponents of 10: $10^{12 - 10}=10^{2}$. So the result is $0.5\times10^{2}$.

Step3: Simplify the result

$0.5\times10^{2}=50$.

Answer:

B. 50
