fraction record: Here 3 – a numerator, 7 – a denominator.
If a numerator is less than a denominator, then the fraction is less than 1 and called a proper fraction. If a
numerator is equal to a denominator, the fraction is equal to 1. If a numerator is greater than a denominator, the
fraction is greater than 1. In both last cases the fraction is called an improper fraction. If a numerator is divisible
by a denominator, then this fraction is equal to a quotient: 63 / 7 = 9. If a division is executed with a
remainder, then this improper fraction can be presented as a mixed number: Math I -7- Feel free to pass this on to your friends, but please don’t post it online.
