Suppose that 53% of us sleep between 7 and 8 hours a day. Express this percent as a decimal.

Question

anonymous · Answer

x% = x/100

So for example,

23% = 23/100

23% = 23/100 = 0.23

which means 23% = 0.23

No, that's how they wanted to trick you, to make it seem more difficult than it is.The question states:
Express this [percent] as a decimal. 

You only had to work with the percent.
