A Story of Numbers
The numbers you have met so far still leave gaps, and rational numbers help fill them. Chapter 1, Rational Numbers, of the NCERT Mathematics textbook for Class 8 revisits numbers writable as one integer over another and studies their behaviour in depth. You will verify closure, commutativity, associativity and distributivity for each operation, find rational numbers packed densely between any two given ones, and represent them on the number line. Word problems from daily transactions show these properties working silently behind ordinary arithmetic.
