6.7 Writing Pure Recurring Decimal into Rational Number Form - II

  1. Remove the decimal point and write the recurring part as the numerator
  2. Write as many nines in the recurring part
  3. Write the fraction in its lowest terms.

Convert 0.56 into a rational number form.
Let x = 0.56
This means x = 0.565656..........I
There are two digits in the recurring decimal part. Hence multiply both sides by 100.
100x = 56.565656.....II
Subtract I from II, we get
99x = 56
x = 56/99
