多分比率の計算です。

Your answer is partially correct.
For about 10 years after the French Revolution, the French government attempted to base measures of time on multiples 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? Assume that the definition of a "day" remains the same.

(a)
(French decimal week) / (standard week) = (10 days) / (7 days) = 10/7

(b)
French decimal second: 1/(10*100*100) day = 1/100000 day
standard second: 1/(24*60*60) day = 1/86400 day
(French decimal second) / (standard second) = 86400/100000 = 108/125
