a)

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

b)

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

404 (3 s.f)
