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

  • 1.0472440945 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 = 1.0472440945


Set up the second equation.

  • Number of decimal places repeating: 9

  • Multiply both sides of the first equation by 109 = 1,000,000,000


y = 1.0472440945

1,000,000,000 × y = 1,000,000,000 × 1.0472440945

1,000,000,000 × y = 1,047,244,094.5472440945


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.

1,000,000,000 × y - y = 1,047,244,094.5472440945 - 1.0472440945 ⇒

(1,000,000,000 - 1) × y = 1,047,244,094.5472440945 - 1.0472440945 ⇒

We now have a new equation:

999,999,999 × y = 1,047,244,093.5


Solve for y in the new equation.

999,999,999 × y = 1,047,244,093.5 ⇒

y = 1,047,244,093.5/999,999,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 1.0472440945

According to our calculations:

y = 1,047,244,093.5/999,999,999

⇒ 1.0472440945 = 1,047,244,093.5/999,999,999


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 10.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

1.0472440945 = (1,047,244,093.5 × 10)/(999,999,999 × 10)

1.0472440945 = 10,472,440,935/9,999,999,990

698,162,729/666,666,666


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.

698,162,729 ÷ 666,666,666 = 1, remainder = 31,496,063 ⇒

698,162,729 = 1 × 666,666,666 + 31,496,063 ⇒

698,162,729/666,666,666 =

(1 × 666,666,666 + 31,496,063) / 666,666,666 =

(1 × 666,666,666) / 666,666,666 + 31,496,063/666,666,666 =

1 + 31,496,063/666,666,666 =
