Which number is a whole number?
a) |-18/9|
b) -4/3
c) 1.6
d) -(-7.963)
Also please explain it to me as well. Thank you.
Whole numbers are integers... numbers you can count using a series 0,1,2,3 ..., etc.
(b), (c) and (d) are obviously not integers. They are fractions or decimals that cannot be reduced to integers.
|-18/9| is the same thing as +2.
That is certainly an integer.
oh okay thank you!

A whole number is a number that is not a fraction or a decimal. It is an integer that is either positive or negative. Let's analyze each option one by one:
a) |-18/9| = |(-2)| = 2. This number is a positive whole number.
b) -4/3 is a fraction, not a whole number. Fractions are not considered whole numbers because they represent parts of a whole.
c) 1.6 is a decimal number, which means it is not a whole number. Whole numbers do not have any decimals or fractional parts.
d) -(-7.963) = 7.963. This number is a positive whole number.
To summarize, the whole numbers in the given options are a) |-18/9| = 2 and d) -(-7.963) = 7.963.
