how do I work this problem: (5)(10^6m) / (3)(10^8m/s)=?

Answer 1

(5/3) * (10^6 m / 10^8 m/s)
(5/3) * 10^-2 s

Yes?

Answer 2

(5)(10^6)m/(3)(10^8)m/s =
Multiply by 1 in the form of s/s and break 10^8 into
(10^6)/(10^2):
(5)(10^6)m*s / (3)(10^6)(10^2)m*s/s =
(5 / 3)(10^6 / 10^6)(1 / 10^2)(m / m)(s / s)s
Cancel the like terms, leaving
5s/3(10^2) =
5s/300
