2. Write the mixed repeating (recurring) decimal number as an improper fraction.

  • 1.63636366 can be written as an improper fraction.

  • The numerator is larger than or equal to the denominator.

Set up the first equation.

  • Let y equal the decimal number:

  • y = 1.63636366


Set up the second equation.

  • Number of decimal places repeating: 5

  • Multiply both sides of the first equation by 105 = 100,000


y = 1.63636366

100,000 × y = 100,000 × 1.63636366

100,000 × y = 163,636.36636366


Subtract the first equation from the second one.

  • Having the same number of decimal places ...
  • The repeating pattern drops off by subtracting the two equations.

100,000 × y - y = 163,636.36636366 - 1.63636366 ⇒

(100,000 - 1) × y = 163,636.36636366 - 1.63636366 ⇒

We now have a new equation:

99,999 × y = 163,634.73


Solve for y in the new equation.

99,999 × y = 163,634.73 ⇒

y = 163,634.73/99,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 1.63636366

According to our calculations:

y = 163,634.73/99,999

⇒ 1.63636366 = 163,634.73/99,999


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 100.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

1.63636366 = (163,634.73 × 100)/(99,999 × 100)

1.63636366 = 16,363,473/9,999,900

5,454,491/3,333,300


4. The fraction is an improper one, rewrite it as a mixed number (mixed fraction):

  • A mixed number = an integer number and a proper fraction, of the same sign.
  • Example 1: 2 1/5; Example 2: - 1 3/7.
  • A proper fraction = the numerator is smaller than the denominator.

5,454,491 ÷ 3,333,300 = 1, remainder = 2,121,191 ⇒

5,454,491 = 1 × 3,333,300 + 2,121,191 ⇒

5,454,491/3,333,300 =

(1 × 3,333,300 + 2,121,191) / 3,333,300 =

(1 × 3,333,300) / 3,333,300 + 2,121,191/3,333,300 =

1 + 2,121,191/3,333,300 =

1 2,121,191/3,333,300
