GCF (3 × 5 × 13 × 6,353 × 8,969; 210 × 510) = 5



Divide both the numerator and the denominator by their GCF.

11,111,111,115/10,000,000,000 =


(3 × 5 × 13 × 6,353 × 8,969)/(210 × 510) =


((3 × 5 × 13 × 6,353 × 8,969) ÷ 5) / ((210 × 510) ÷ 5) =


(3 × 13 × 6,353 × 8,969)/(210 × 59) =


2,222,222,223/2,000,000,000


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.

2,222,222,223 ÷ 2,000,000,000 = 1, remainder = 222,222,223 ⇒


2,222,222,223 = 1 × 2,000,000,000 + 222,222,223 ⇒


2,222,222,223/2,000,000,000 =


(1 × 2,000,000,000 + 222,222,223) / 2,000,000,000 =


(1 × 2,000,000,000) / 2,000,000,000 + 222,222,223/2,000,000,000 =


1 + 222,222,223/2,000,000,000 =


1 222,222,223/2,000,000,000
