2. Write the number as an improper fraction.
- 8.96 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:
8.96 = 8.96/1
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.
8.96/1 =
(8.96 × 100)/(1 × 100) =
896/100
3. Reduce (simplify) the fraction above:
896/100
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).
896 = 27 × 7
100 = 22 × 52
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (27 × 7; 22 × 52) = 22
Divide both the numerator and the denominator by their GCF.
896/100 =
(27 × 7)/(22 × 52) =
((27 × 7) ÷ 22) / ((22 × 52) ÷ 22) =
(25 × 7)/52 =
224/25
