help would be greatly appreciated :)
150 x 10^9 m
= 1.50 x 10² x 10^9 m
= 1.50 x 10^(2 + 9) m
= 1.50 x 10^11 m
370300 km
= 370300 x 10³ m
= 3703 x 10^5 m
Difference in distance
= 1.50 x 10^11 m - 3703 x 10^5 m
= (1.50 x 10^6) x 10^5 m - 3703 x 10^5 m
= (150 0000 - 3703) x 10^5 m
= 149 6297 x 10^5 m
149 6297 x 10^5 m ÷ (3703 x 10^5 m)
= 1496297 ÷ 3703
≈ 404.076965
