• Hi, what do ypu call a fraction that has a numerator bigger than the denominator?

• A fraction with a bigger numerator is called an improper fraction. A fraction with a bigger denominator than numerator is called a proper fraction. See the difference? 1/12 would be considered a proper fraction since the numerator (1) is less than the denominator (12). But if I had the fraction 13/12, it would be considered an improper fraction since the numerator (13) is greater than it's denominator (12). Another fraction is a mixed fraction. A mixed fraction is a fraction with a whole number and a fraction. 1 1/12 is mixed fraction. There is a 1, which is a whole number, and there is the fraction 1/12, which is a fraction. Ther fraction and whole number together make a mixed fraction.
• How are the numerator and denominator of a fraction related to the number of equal parts from 0 to 1 ? Am a bit confused. Thx.
• The denominator tells us how many equal parts we make between 0 and 1 on a number line and
the numerator tells us which is the part we wanted to mark. Hope this helps.
• you did a good job on that video!!
