Theory:

Let us consider 64 and 64. First, let us plot  64.
                     
  • Here, the numerator \(6\) is greater than the denominator \(4\).
  • Then, we have to convert it into a mixed fraction.
  • A mixed fraction of 64 is 124.
  • Now, let us draw a number line and plot \(1, -1\) and \(2, -2.\)
  • Then the number 124 has to lie somewhere between \(1\) and \(2\).
  • Now we divide the length between \(1\) and \(2\) into equal parts.
  • The Denominator gives us the number of equal parts.
  • It is \(4\), so we divide it into \(4\) equal parts.

  • The numerator tells us the number of parts starting from \(1\).
  • Here, it is \(2\). So we mark the point \(2\) parts away from the \(1\).

Similarly,  64 can be marked using the same procedure because 64 is the corresponding value of 64.
  • We know that it lies between \(-1\) and \(-2\). So, we divide it into four equal parts and mark \(2\) parts away from the \(-1.\)
