Question

A cat spends about 7 out of 10 hours sleeping about what percent of a cat's day is spent sleeping

Answer 1

I understand that it means that out of every 10 hours, a cat spends 7 sleeping (not 7 hours in a day).


this means that a cat is sleeping$\frac{7}{10}*100%=70%$

a percentage stays constant, this means that a cat sleeps 70 % of each 10 hours, but also 70% of the day.
