What do you mean by real number?

real number, in mathematics, a quantity that can be expressed as an infinite decimal expansion. Real numbers are used in measurements of continuously varying quantities such as size and time, in contrast to the natural numbers 1, 2, 3, …, arising from counting.

Is 1.8 a real number?

Certain Decimals Consider the number 1.8. This decimal terminates, because it only has one place value past the decimal. Thus we can convert it to a fraction like so: 1.8=1.81=1.81⋅1010=1.8⋅101⋅10=1810 We know that 18 and 10 are integers and 10 is nonzero, so 1.8=1810 is rational.
