2. Write the number as a proper fraction.
- 0.222222222224 can be written as a proper fraction.
- A proper fraction = the numerator is smaller than the denominator..
Write down the number divided by 1, as a fraction:
0.222222222224 = 0.222222222224/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 1,000,000,000,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
0.222222222224/1 =
(0.222222222224 × 1,000,000,000,000)/(1 × 1,000,000,000,000) =
222,222,222,224/1,000,000,000,000
3. Reduce (simplify) the fraction above:
222,222,222,224/1,000,000,000,000
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).
222,222,222,224 = 24 × 1,667 × 8,331,667
1,000,000,000,000 = 212 × 512
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (24 × 1,667 × 8,331,667; 212 × 512) = 24
Divide both the numerator and the denominator by their GCF.
222,222,222,224/1,000,000,000,000 =
(24 × 1,667 × 8,331,667)/(212 × 512) =
((24 × 1,667 × 8,331,667) ÷ 24) / ((212 × 512) ÷ 24) =
(1,667 × 8,331,667)/(28 × 512) =
13,888,888,889/62,500,000,000
