Question

0.5 is 30 minutes how do I work out more times e.g. How many minutes is 0.45 or 0.48 I don't know how to do it help

Answer 1

I dont know if this will help you, but a 15th (.15) of an hour is 9 minutes!
So it'd be
.15=9 minutes
.30=18 minutes
.45=27
.60=36
.75=45 
.90=54
and obviously
1.0 is 60 minutes
(((EVERY .05 IS THREE MINUTES))))
