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

  • 74.246 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 = 74.246


Set up the second equation.

  • Number of decimal places repeating: 1

  • Multiply both sides of the first equation by 101 = 10


y = 74.246

10 × y = 10 × 74.246

10 × y = 742.46

Get the same number of decimal places as for y:

10 × y = 742.466

Note: 742.466 = 742.46


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.

10 × y - y = 742.466 - 74.246 ⇒

(10 - 1) × y = 742.466 - 74.246 ⇒

We now have a new equation:

9 × y = 668.22


Solve for y in the new equation.

9 × y = 668.22 ⇒

y = 668.22/9

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 74.246

According to our calculations:

y = 668.22/9

⇒ 74.246 = 668.22/9


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.

74.246 = (668.22 × 100)/(9 × 100)

74.246 = 66,822/900


3. Reduce (simplify) the fraction above:
66,822/900
to the lowest terms, to its simplest equivalent form, irreducible.

To reduce a fraction to the lowest terms divide the numerator and denominator by their greatest (highest) common factor (divisor), GCF.


Factor the numerator and denominator (prime factorization).

66,822 = 2 × 3 × 7 × 37 × 43

900 = 22 × 32 × 52

Calculate the greatest (highest) common factor (divisor), GCF.

Multiply all the common prime factors by the lowest exponents.

GCF (2 × 3 × 7 × 37 × 43; 22 × 32 × 52) = 2 × 3


» Calculate the greatest (highest) common factor (divisor), GCF, online calculator


Divide both the numerator and the denominator by their GCF.

66,822/900 =

(2 × 3 × 7 × 37 × 43)/(22 × 32 × 52) =

((2 × 3 × 7 × 37 × 43) ÷ (2 × 3)) / ((22 × 32 × 52) ÷ (2 × 3)) =

(7 × 37 × 43)/(2 × 3 × 52) =

11,137/150


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.

11,137 ÷ 150 = 74, remainder = 37 ⇒

11,137 = 74 × 150 + 37 ⇒

11,137/150 =

(74 × 150 + 37) / 150 =

(74 × 150) / 150 + 37/150 =

74 + 37/150 =

74 37/150


11,137/150 ~ Equivalent fractions.

  • The above fraction cannot be reduced.
  • That is, it has the smallest possible numerator and denominator.
