245,787,878 = 2 × 7 × 17,556,277
10,000,000 = 27 × 57
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 7 × 17,556,277; 27 × 57) = 2
Divide both the numerator and the denominator by their GCF.
245,787,878/10,000,000 =
(2 × 7 × 17,556,277)/(27 × 57) =
((2 × 7 × 17,556,277) ÷ 2) / ((27 × 57) ÷ 2) =
(7 × 17,556,277)/(26 × 57) =
122,893,939/5,000,000
4. The fraction is an improper one, rewrite it as a mixed number (mixed fraction):
- A mixed number = an integer number and a proper fraction, of the same sign.
- Example 1: 2 1/5; Example 2: - 1 3/7.
- A proper fraction = the numerator is smaller than the denominator.
122,893,939 ÷ 5,000,000 = 24, remainder = 2,893,939 ⇒
122,893,939 = 24 × 5,000,000 + 2,893,939 ⇒
122,893,939/5,000,000 =
(24 × 5,000,000 + 2,893,939) / 5,000,000 =
(24 × 5,000,000) / 5,000,000 + 2,893,939/5,000,000 =
24 + 2,893,939/5,000,000 =
24 2,893,939/5,000,000
