2. Write the number as a proper fraction.
- 0.36 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:
0.36 = 0.36/1
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.
0.36/1 =
(0.36 × 100)/(1 × 100) =
36/100
3. Reduce (simplify) the fraction above:
36/100
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).
36 = 22 × 32
100 = 22 × 52
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (22 × 32; 22 × 52) = 22
Divide both the numerator and the denominator by their GCF.
36/100 =
(22 × 32)/(22 × 52) =
((22 × 32) ÷ 22) / ((22 × 52) ÷ 22) =
32/52 =
9/25
