The mass of Uranus is about $8.7 \times 10^{22}$ $8.7 times 10^22$ metric tons. The mass of the sun is about $1.998 \times 10^{27}$ $1.998 times 10^27$ metric tons. About how many times the mass of Uranus is the mass of the sun?

Mass of Sun is $2.297 \times 10^{4}$ $2.297xx10^4$ times mass of Uranus

As the mass of the Sun is $1.998 \times 10^{27}$ $1.998xx10^27$ metric tons

and mass of Uranus is $8.7 x 10^{22}$ $8.7x10^22$ metric tons

Mass of Sun is $\frac{1.998 \times 10^{27}}{8.7 \times 10^{22}}$ $(1.998xx10^27)/(8.7xx10^22)$ times mass of Uranus or

$\frac{1.998}{8.7} \times 10^{27 - 22}$ $1.998/8.7xx10^(27-22)$ times or

$0.2297 \times 10^{5}$ $0.2297xx10^5$ or $2.297 \times 10^{4}$ $2.297xx10^4$ times.

The mass of Uranus is about 8.7×10228.7 times 10^22 metric tons. The mass of the sun is about 1.998×10271.998 times 10^27 metric tons. About how many times the mass of Uranus is the mass of the sun?
