A French Week
For about 10 years after the French Revolution, the French government attempted to base measures of time on multiple of ten: One week consisted of 10 days, one day consisted of 10 hours, one hour consisted of 100 minutes, and one minute consisted of 100 seconds. What are the ratios of (a) the French decimal week to the standard week and (b) the French decimal second to the standard second?
So the ratio is 1.65, but the answers say that it is 1.43 ?
Also, in the first question I assumed that the 'French' second was the same as the 'normal' second, so wouldn't my answer to the second question make the answer to my first question invalid? Thanks.
Why wouldn't DivideByZero's calculations be correct? When comparing two terms of measurement, you must relate them somehow

The only unit that both systems agree upon is the length of one day.

Thanks, I don't know why I thought days could be of different lengths.
