The percentage of a cat's day spent sleeping is 70% if the cat spends about 7 out of 10 hours sleeping.
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
A cat spends about 7 out of 10 hours sleeping.
As we know, from the definition of the percentage, the ratio of two integers is stated as a fraction of a hundred parts. It is a metric for comparing two sets of data,
The percentage of a cat's day spent sleeping = (7/10)x100
The percentage of a cat's day spent sleeping = (0.7)x100
The percentage of a cat's day spent sleeping = 70%
Thus, the percentage of a cat's day spent sleeping is 70% if the cat spends about 7 out of 10 hours sleeping.

To answer the problem, the coins of Janice must be a penny, dime, and a nickel which total up to $0.16, while Jeremy's coins are three dimes and two pennies totaling $0.32
The problem can be approached by considering the different coins you have available and their values. In the U.S, these are penny ($0.01), nickel ($0.05), dime ($0.10), quarter ($0.25), half dollar ($0.50), and dollar ($1.00). Because Jeremy's coins are all the same and twice Jane's total, this limits us to lower value coins.
Let's start with Jane. She can't have a quarter because Jeremy doesn’t have $0.50 coins. If she had a dime, Jeremy would need two dimes but we know all his coins are the same so this isn't possible. This means Jane must have a penny ($0.01), a nickel ($0.05) and a dime ($0.10) for a total of $0.16. Therefore, Jeremy, whose total is twice Jane's, must have $0.32 which can be achieved by having three dimes ($0.10 x 3 = $0.30) and two pennies ($0.01 x 2 = $0.02).
