2. Write the number as a proper fraction.
- 0.630300110138 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:
0.630300110138 = 0.630300110138/1
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.
0.630300110138/1 =
(0.630300110138 × 1,000,000,000,000)/(1 × 1,000,000,000,000) =
630,300,110,138/1,000,000,000,000
3. Reduce (simplify) the fraction above:
630,300,110,138/1,000,000,000,000
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).
630,300,110,138 = 2 × 41 × 7,686,586,709
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 (2 × 41 × 7,686,586,709; 212 × 512) = 2
Divide both the numerator and the denominator by their GCF.
630,300,110,138/1,000,000,000,000 =
(2 × 41 × 7,686,586,709)/(212 × 512) =
((2 × 41 × 7,686,586,709) ÷ 2) / ((212 × 512) ÷ 2) =
(41 × 7,686,586,709)/(211 × 512) =
315,150,055,069/500,000,000,000
