- 0.156264 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:
0.156264 = 0.156264/1
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.
0.156264/1 =
(0.156264 × 1,000,000)/(1 × 1,000,000) =
156,264/1,000,000
3. Reduce (simplify) the fraction above:
156,264/1,000,000
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).
156,264 = 23 × 3 × 17 × 383
1,000,000 = 26 × 56
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (23 × 3 × 17 × 383; 26 × 56) = 23
Divide both the numerator and the denominator by their GCF.
156,264/1,000,000 =
(23 × 3 × 17 × 383)/(26 × 56) =
((23 × 3 × 17 × 383) ÷ 23) / ((26 × 56) ÷ 23) =
(3 × 17 × 383)/(23 × 56) =
19,533/125,000
