2. Write the number as an improper fraction.
- 6.35 can be written as an improper fraction.
- An improper fraction = the numerator is larger than or equal to the denominator..
Write down the number divided by 1, as a fraction:
6.35 = 6.35/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 100.
- 1 followed by as many 0-s as the number of digits after the decimal point.
6.35/1 =
(6.35 × 100)/(1 × 100) =
635/100
3. Reduce (simplify) the fraction above:
635/100
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).
635 = 5 × 127
100 = 22 × 52
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (5 × 127; 22 × 52) = 5
Divide both the numerator and the denominator by their GCF.
635/100 =
(5 × 127)/(22 × 52) =
((5 × 127) ÷ 5) / ((22 × 52) ÷ 5) =
127/(22 × 5) =
127/20
