This paper focuses on the definitions and the mis-out and mis-in examples of rational numbers that four prospective elementary teachers presented while working on rational number assignments. The participants were first asked to respond, individually, to an Individual Rational Number Assignment, ...
Question: Give an example of real numbers {eq}a {/eq} and {eq}b {/eq} satisfying the following condition: {eq}csc(a) = \dfrac{1}{cos(b)} {/eq}. Reciprocal Trigonometric Identity: The reciprocal trigonometric identity states that the reciprocal of sine is co...
We have to convert ở and [ into equlvalent rational numbers having commondenominator.Clearly, such a denominator is the LCM of 9 and 6.We have,9 = 3 × 3 and 6 = 2 × 3Therefore, LCM of 9 and 6 is 2 × 3 × 3 = 18Now,18 -9 = 2 and 18 =6 = 3Therefore, Ả = 3...
A rational number is one that can be expressed as a ratio of two integers, say n/m with m≠0. The integers are included among the rational numbers, when n is divisible by m. Also, rational numbers have alternative forms, for example, 2/3 = 4/6 = 6/9, etc. Let us focus on ra...

Let us consider an example to clarify these definitions. Let the original statement be: If x is a rational number, then x2 is a rational number. Its converse is the statement “If x2 is a rational number, then x2 is a rational number.” Its inverse is the statement “If x is not...
