- A proper fraction = the numerator is smaller than the denominator..
Write down the number divided by 1, as a fraction:
0.18282828284 = 0.18282828284/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 100,000,000,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
0.18282828284/1 =
(0.18282828284 × 100,000,000,000)/(1 × 100,000,000,000) =
18,282,828,284/100,000,000,000
3. Reduce (simplify) the fraction above:
18,282,828,284/100,000,000,000
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).
18,282,828,284 = 22 × 7 × 15,083 × 43,291
100,000,000,000 = 211 × 511
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (22 × 7 × 15,083 × 43,291; 211 × 511) = 22
Divide both the numerator and the denominator by their GCF.
18,282,828,284/100,000,000,000 =
(22 × 7 × 15,083 × 43,291)/(211 × 511) =
((22 × 7 × 15,083 × 43,291) ÷ 22) / ((211 × 511) ÷ 22) =
(7 × 15,083 × 43,291)/(29 × 511) =
4,570,707,071/25,000,000,000
