    A number that can be written as a fraction is called a(n) _________ number.

    Explanation
    A number that can be written as a fraction is called a rational number. This includes both whole numbers and decimals that can be expressed as a ratio of two integers. The term "rational" refers to the fact that these numbers can be expressed as a ratio or fraction.

    A number with a repeating decimal is a(n) ______________ number.

    Explanation
    A number with a repeating decimal is called a rational number. Rational numbers can be expressed as a fraction, where the numerator and denominator are both integers. Repeating decimals can be written as fractions with repeating patterns. Therefore, a number with a repeating decimal is considered rational. Real numbers, on the other hand, include both rational and irrational numbers, so the statement "a number with a repeating decimal is a real number" is also true.

    True for False:  All Rational numbers are Real numbers.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    All rational numbers are real numbers because rational numbers can be expressed as fractions of two integers, and the set of real numbers includes all rational numbers along with irrational numbers. Rational numbers can be plotted on a number line and are part of the continuous number line that represents real numbers. Therefore, it is true that all rational numbers are real numbers.

    True or False: All Real numbers are Rational numbers.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement "All Real numbers are Rational numbers" is false. While all rational numbers are real numbers, not all real numbers are rational. Real numbers include both rational numbers (which can be expressed as a fraction) and irrational numbers (which cannot be expressed as a fraction, such as √2 or π). Therefore, the statement is incorrect.

     is which types of numbers?  Check all that apply. - ProProfs

     is which types of numbers?  Check all that apply.

    • Real

    • Rational

    • Irrational

    Correct Answer(s)
    A. Real
    A. Rational
    Explanation
    Real numbers are a set of numbers that include all rational and irrational numbers. Rational numbers are numbers that can be expressed as a fraction, where the numerator and denominator are integers. Irrational numbers, on the other hand, cannot be expressed as a fraction and have non-repeating, non-terminating decimal representations. Therefore, the correct answer is Real and Rational, as all rational numbers are real numbers.

    Correct Answer(s)
    A. 6
    A. -17
    A. 82.4
    A.
    A.
    Explanation
    The numbers 6, -17, and 82.4 are all real numbers. Real numbers include all rational and irrational numbers, which means they can be expressed as a fraction or a decimal. In this case, 6 is a whole number, -17 is a negative whole number, and 82.4 is a decimal number. Therefore, all three numbers fall under the category of real numbers.

     is which types of numbers?  Check all that apply.

    • Real

    • Rational

    • Irrational

    Correct Answer(s)
    A. Real
    A. Irrational
    Explanation
    Real numbers are a set of numbers that include all rational and irrational numbers. Rational numbers are numbers that can be expressed as a fraction, while irrational numbers cannot be expressed as a fraction and have non-repeating, non-terminating decimal representations. Therefore, the answer "Real, Irrational" is correct because it includes both types of numbers.

    Rate this question:

  • 9. 

    Which of the following are Rational numbers?

    • 93

    • -12

    • 0

    • -4.8

    Correct Answer(s)
    A. 93
    A. -12
    A. 0
    A. -4.8
    Explanation
    All the given numbers are rational numbers. A rational number is any number that can be expressed as a fraction or a ratio of two integers. 93, -12, and 0 are all integers, and any integer can be expressed as a fraction by dividing it by 1. -4.8 can be expressed as the fraction -48/10, which can be simplified to -24/5. Therefore, all the given numbers can be expressed as fractions or ratios of integers, making them rational numbers.
