2. Write the number as a proper fraction.
- 0.00045516615 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:
0.00045516615 = 0.00045516615/1
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.
0.00045516615/1 =
(0.00045516615 × 100,000,000,000)/(1 × 100,000,000,000) =
45,516,615/100,000,000,000
3. Reduce (simplify) the fraction above:
45,516,615/100,000,000,000

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).
45,516,615 = 3 × 5 × 3,034,441
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 (3 × 5 × 3,034,441; 211 × 511) = 5
Divide both the numerator and the denominator by their GCF.
45,516,615/100,000,000,000 =
(3 × 5 × 3,034,441)/(211 × 511) =
((3 × 5 × 3,034,441) ÷ 5) / ((211 × 511) ÷ 5) =
(3 × 3,034,441)/(211 × 510) =
9,103,323/20,000,000,000
