1.) An irrational number is a number that is part of the whole number system. True or false?

2.) True or false....The fraction 7/8 is a terminating decimal.1.) An irrational number is a number that is part of the whole number system. True or false?
1. false


whole number = {0, 1, 2, 3, ...}


irrational numbers are numbers such as pi, e which aren't part of the set of whole numbers. They are part of the set of real numbers.


2. true


7/8 = .875 (decimal terminates)1.) An irrational number is a number that is part of the whole number system. True or false?
1) False. A whole number, like 3, can always be written as a ratio like this: 3/1. So, any number that can't be written as a ratio (called an irrational number) can't do what a whole number can do, so it's not a whole number.





2) True. The denominator has only twos and fives multiplied together (8 = 2*2*2), so it will terminate. Numbers like 1/3 don't terminate, since 3 isn't a bunch of twos and fives multiplied together.
1.) FALSE - are NOT whole numbers, they are decimals that neither repeat, nor terminate


2.) TRUE - 7/8 = 0.875
