Answer
C. 86 times larger
Step-by-step explanation
To compare the mass of the Earth with respect to the mass of the Moon we need to divide both masses and simplify as follows:
[tex]\begin{gathered} \frac{mass\text{ of the Earth}}{mass\text{ of the Moon}}= \\ =\frac{6\times10^{24}}{7\times10^{22}} \\ =\frac{6}{7}\times\frac{10^{24}}{10^{22}} \\ =\frac{6}{7}\times10^{24-22} \\ \approx0.86\times10^2 \\ \operatorname{\approx}0.86\times100 \\ \operatorname{\approx}86 \end{gathered}[/tex]
