2. Write the number as a proper fraction.
- 0.0551512 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:
0.0551512 = 0.0551512/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 10,000,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
0.0551512/1 =
(0.0551512 × 10,000,000)/(1 × 10,000,000) =
551,512/10,000,000
3. Reduce (simplify) the fraction above:
551,512/10,000,000
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).
551,512 = 23 × 13 × 5,303
10,000,000 = 27 × 57
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (23 × 13 × 5,303; 27 × 57) = 23
Divide both the numerator and the denominator by their GCF.
551,512/10,000,000 =
(23 × 13 × 5,303)/(27 × 57) =
((23 × 13 × 5,303) ÷ 23) / ((27 × 57) ÷ 23) =
(13 × 5,303)/(24 × 57) =
68,939/1,250,000
