- 0.694448 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:
0.694448 = 0.694448/1
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.
- 1 followed by as many 0-s as the number of digits after the decimal point.
0.694448/1 =
(0.694448 × 1,000,000)/(1 × 1,000,000) =
694,448/1,000,000
3. Reduce (simplify) the fraction above:
694,448/1,000,000
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).
694,448 = 24 × 43,403
1,000,000 = 26 × 56
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (24 × 43,403; 26 × 56) = 24
Divide both the numerator and the denominator by their GCF.
694,448/1,000,000 =
(24 × 43,403)/(26 × 56) =
((24 × 43,403) ÷ 24) / ((26 × 56) ÷ 24) =
43,403/(22 × 56) =
43,403/62,500
