      Rational Numbers and Proportional Reasoning I ntegers such as -5 were invented to solve equations like x + 5 = 0. Similarly, a different type of number is needed to solve the equation 2x = 1. We need notation for this new number. If mul-tiplication is to work with this new type of number as with whole numbers, then 2x = x + x = 1. In other ...

      The reciprocal of 0 is 1/0 which is not defined. Therefore, 0 is a rational number that does not have a reciprocal. (ii) The reciprocal ofa/b isb/a. The reciprocal of 1 and –1 is 1 and –1 respectively. Therefore, 1 and –1 are the rational numbers that are equal to their reciprocals. (iii) Negative of 0 is again 0.

      Numbers are often visualized using the “number line”, , where the distance on the line from 0 to 1 is thought of as one ”unit”, the distance from 0 to 2 as two lengths of one unit and so on. The arrow to the right on the number line implies that 7, 8, 9 etc. will follow. For now, the line is only the “points” at 0, at 1, at 2 and so on.
