1. No.

Honestly, I don't believe you.

I will do two as examples of the unit conversion process.

12. 12.5 deciliters( 1 liter/10 deciliters)=125 liters (notice the deciliters divide out).

15. 504,576,000seconds(1hr/3600sec)(1day/24hr)(1year/365days)=
504,576,000/(360*24*365) years

1 is done this way.
6.5 hr/day for 5 day = 32.5 hrs

There are 60 minutes in an hour
There are 60 seconds in a minute.
Put all of that together in the form of dimensional analysis to obtain
32.5 hr x (60 min/hr) x (60 s/min) = 117000 s.
