Q. Which of the following are rational numbers?Multi-select Choices:(A) 0(B) 3.8(C) 10(D)β Ο
Define rational number: Step 1: Define a rational number.A rational number can be expressed as a fractions" target="_blank" class="backlink">fraction where both the numerator and the denominator are integers, and the denominator is not zero. Rational numbers include integers, fractions, and terminating or repeating decimals.
Analyze choice (A): Step 2: Analyze choice (A) which is 0. 0 can be expressed as 10β, where 0 is the numerator and 1 is the denominator. Since both are integers and the denominator is not zero, 0 is a rational number.
Analyze choice (B): Step 3: Analyze choice (B) which is 3.8. 3.8 is a terminating decimal and can be expressed as 1038β, which simplifies to 519β. Both 19 and 5 are integers, and the denominator is not zero, so 3.8 is a rational number.
Analyze choice (C): Step 4: Analyze choice (C) which is 10. 10 is an integer and can be expressed as 110β. Since both 10 and 1 are integers and the denominator is not zero, 10 is a rational number.
Analyze choice (D): Step 5: Analyze choice (D) which is Ο (pi).Ο is known to be an irrational number because it cannot be expressed as a fraction of two integers. Its decimal representation is non-terminating and non-repeating.
