- 0.12222224 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:
0.12222224 = 0.12222224/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 100,000,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
0.12222224/1 =
(0.12222224 × 100,000,000)/(1 × 100,000,000) =
12,222,224/100,000,000
3. Reduce (simplify) the fraction above:
12,222,224/100,000,000
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).
12,222,224 = 24 × 7 × 29 × 53 × 71
100,000,000 = 28 × 58
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (24 × 7 × 29 × 53 × 71; 28 × 58) = 24
Divide both the numerator and the denominator by their GCF.
12,222,224/100,000,000 =
(24 × 7 × 29 × 53 × 71)/(28 × 58) =
((24 × 7 × 29 × 53 × 71) ÷ 24) / ((28 × 58) ÷ 24) =
(7 × 29 × 53 × 71)/(24 × 58) =
763,889/6,250,000
