1. To explain why you have to change the sign < into > (and vice versa) by multipling with a negative number, I'll show you an example:
3 < 5 is true. Now multiply both sides by (-2) and you'll get:
-6 > -10. Because (-10) is smaller then (-6) or in other words (-6) is greater then (-10) you have to change < into >.
2. This fraction (log 4.6 / log 0.3) is not the same as (log 0.3 / log 4.6) but your result is correct. But you don't have to change the ">"-sign because you don't multiply both sides of your inequality by a negative number.
So the result is:
