Choose the number below that fits into ALL the following number sets: Natural Number Whole Number Integer

answer choices: select the one that is 100% correct

1.9
-2/3
6x - 3x
5

what is the 100% correct option

1 answer

To determine which number fits into all the specified sets (Natural Number, Whole Number, and Integer), we need to analyze each option:

  1. 1.9: This is a decimal number and not a natural number, whole number, or integer.

  2. -2/3: This is a negative fraction, which is not a natural number, whole number, or integer.

  3. 6x - 3x: This simplifies to \(3x\). This expression depends on the value of \(x\). If \(x\) is a natural number, then \(3x\) would also be a natural number, whole number, and integer for those values. However, we cannot definitively classify \(3x\) without knowing \(x\).

  4. 5: This is a natural number (it's a positive integer), a whole number (non-negative integers include natural numbers), and also an integer (whole numbers plus negatives include all integers).

The only number that fits into all three sets (Natural Number, Whole Number, and Integer) is 5.

So, the 100% correct option is 5.
