Any legal fraction (denominator not equal to zero) with a numerator equal to zero has an overall value of zero. This means , , all have a fraction value of zero because the numerators are equal to zero.
Can a numerator be negative?
Usually, the negative sign is placed in front of the fraction, but you will sometimes see a fraction with a negative numerator or denominator. If both the numerator and denominator are negative, then the fraction itself is positive because we are dividing a negative by a negative.
How to calculate the fraction of the numerator?
1 List the prime factors of the numerator and denominator. 2 Find the factors common to both the numerator and denominator. 3 Divide the numerator and denominator by all common factors (called canceling).
How are fractions reduced to their lowest terms?
A fraction is reduced to lowest terms, or simplified, when its numerator and denominator have no common factors. It’s easier to multiply, divide, add and subtract fractions when they’re simplified. To simplify a fraction, we find an equivalent fraction where the numerator and denominator have no common factors.
What happens when you simplify the numerator of a fraction?
Notice that when you simplify a fraction, you divide the numerator and denominator by the same number, in the same way you multiply by the same number to find an equivalent fraction with a greater denominator. In the example above, you could have divided the numerator and denominator by 9, a common factor of 54 and 72.
Which is the best definition of an improper fraction?
Improper Fraction – A fraction whose numerator is equal to or greater than its denominator. Least Common Denominator – The least common multiple of the denominators of two or more fractions. That is, the lowest number which is a multiple of both denominators.
