A rational number can't be a decimal that repeats.
-
True
-
False
Correct Answer
A. FalseExplanation
This statement is false. A rational number can indeed be a decimal that repeats. Rational numbers are numbers that can be expressed as a fraction, where the numerator and denominator are both integers. Many fractions, when expressed as decimals, result in repeating decimals. For example, 1/3 is equal to 0.3333..., where the digit 3 repeats indefinitely. Therefore, a repeating decimal can be a rational number.Rate this question:

All square roots are irrational numbers.
-
True
-
False
Correct Answer
A. FalseExplanation
The statement "All square roots are irrational numbers" is false. While it is true that some square roots, such as √2 or √3, are irrational, there are also square roots that are rational. For example, the square root of 4 is 2, which is a rational number. Therefore, not all square roots are irrational.Rate this question:

Which is the algebraic expression for twelve less than x?
-
X - 12
-
12 - x
Correct Answer
A. X - 12Explanation
The algebraic expression for "twelve less than x" is x - 12. The phrase "less than" indicates subtraction, and when we say "twelve less than x," it means we are subtracting 12 from the value of x. Therefore, the expression is x - 12. The option "12 - x" would mean 12 subtracted by x, which is not the same as "twelve less than x."Rate this question:

What is the algebraic expression for the product of 6 and t?
-
6t
-
6/t
-
6 - t
-
T - 6
Correct Answer
A. 6tExplanation
The algebraic expression for "the product of 6 and t" is 6t. The term "product" refers to multiplication. Therefore, when we say "the product of 6 and t," we multiply 6 and t, which is represented as 6t. The option "6/t" represents division, "6 - t" represents subtraction, and "t - 6" also represents subtraction, none of which correctly express the product of 6 and t.Rate this question:

Which statement below describes this equation? 5(x - 4)
-
Five times x minus 4
-
The product of five and the difference of x and 4
-
Five x less than 4
Correct Answer
A. The product of five and the difference of x and 4Explanation
The equation 5(x - 4) represents the product of five and the difference of x and 4. This can be understood by breaking down the equation: 5 multiplied by (x - 4). The term (x - 4) represents the difference between x and 4, and multiplying it by 5 gives the product of five and the difference of x and 4.Rate this question:

8 / 24 is a reduced fraction.
-
True
-
False
Correct Answer
A. FalseExplanation
The given statement is false. A reduced fraction is a fraction in which the numerator and denominator have no common factors other than 1. In the given fraction 8/24, both 8 and 24 can be divided by 8 to get 1/3, which is a reduced fraction. Therefore, the statement is incorrect.Rate this question:

-
Integers
-
Natural numbers
-
Whole numbers
-
Fractions
Correct Answer
A. IntegersExplanation
Integers include all positive and negative whole numbers, as well as zero. Natural numbers are positive numbers starting from 1, whole numbers include zero and positive numbers, and fractions represent parts of a whole.Rate this question:

Decimals that do not stop are called ________________________.
-
Terminating decimals
-
Repeating decimals
-
Non-terminating decimals
-
Rational numbers
Correct Answer
A. Non-terminating decimalsExplanation
Non-terminating decimals are decimals that continue infinitely without ending. Terminating decimals come to an end after a certain number of digits. Repeating decimals are a type of non-terminating decimal where a specific sequence of digits repeats indefinitely. Rational numbers are numbers that can be expressed as a fraction of two integers.Rate this question:

Rational numbers are the numbers that can be written as a _______________.
-
Whole number
-
Decimal
-
Fraction
-
Irrational number
Correct Answer
A. FractionExplanation
Rational numbers are numbers that can be written as the ratio (fraction) of two integers (where the denominator is not zero). Whole numbers are a subset of rational numbers, decimals can be either rational or irrational, and irrational numbers cannot be expressed as fractions of integers.Rate this question:
