Question

which set of numbers best describes the displayed weights on a digtal scle that shows each weight to the nearesst half pound? a whole numbers b rational numbers c real numbers d integers

Answer 1

Weight on this digital scale is able to show the half pound (or .5)

Whole numbers and integers can not have a fraction or decimal. (1, 5, 11)

Rational numbers are numbers can be expressed as fractions or decimals.

Real numbers can as well but they can also include irrational numbers.

I believe rational numbers best expresses this problem.
