Real Numbers (16 A) Real Numbers (16 A) Testing prior knowledge on Rational and Irrational Numbers 1 / 10 Simplify -1/2 + 5/6 – 1/4 + 1/12 Check 2 / 10 Which statement is always true? Every non-terminating decimal can be written as a fraction. Every decimal that can be written as a fraction must terminate. Every terminating or non-terminating repeating decimal can be written as a fraction. Every non-terminating non-repeating decimal can be written as a fraction. 3 / 10 A teacher displays these numbers on the board: 0.121212…, 0.123456789101112…, 0.8, 0.777777… How many of them can be written as fractions? 1 2 3 4 4 / 10 Which decimal cannot be expressed in the form q/p, where p, q are integers and q=0? 0.625 1.272727… 3.14159265358979… 0.090909… 5 / 10 If x=0.272727… and y=0.275275275…, which statement is correct? Both are terminating decimals. x is terminating and y is non-terminating repeating. Both are non-terminating repeating decimals. x is non-terminating non-repeating and y is repeating. 6 / 10 A student says that 0.125252525… is a non-terminating non-repeating decimal because it does not have the same digit repeating from the beginning. Is the student correct? Yes, because the decimal never terminates. Yes, because more than one digit is repeating. No, because 25 repeats indefinitely after the initial 1 No, because every decimal is either terminating or repeating. 7 / 10 Identify whether π (pi) is rational or irrational. Rational Irrational 8 / 10 Can real numbers be both positive and negative? True False 9 / 10 Which two types of numbers combine to form the set of real numbers? Rational numbers + Irrational numbers Rational numbers + Natural numbers Irrational numbers + Whole numbers Natural Numbers + Real Numbers 10 / 10 Which option correctly classifies all three numbers? 7/20, 5/18, 2 Terminating, repeating, non-repeating Repeating, terminating, non-repeating Terminating, non-repeating, repeating Non-repeating, repeating, terminating Your score isThe average score is 0%
