Common Denominator

• A common Denominator is when two fractions, share the same number under, the fraction line.

• Example One: ¼ and ¾, 4 is the common denominator.

• Example Two: 1/5 and 2/5, 5 is the common denominator.

Discount

• A discount is where you get some money off for example from the original price. So its basically like the item is cheaper than its original price.

• Example one: Get 50% off everything in the store.

• Example two: On black Friday only 75% off all toys.

Simplest form

• Simplest form is where a fraction for example can not be reduced any more.

• Example two: ¾ is also in simplest form, since that is not reducible anymore.

Proper fraction

• A proper fraction is when the numerator ( the top part of the fraction) is smaller than the denominator ( the bottom part of the fraction)

• 1/5 is a proper fraction because the numerator is smaller than the denominator.

• 9/10 is also a proper fraction because the numerator is smaller than the denominator.

Improper fraction• An improper fraction is when the numerator ( the top part of the fraction) is

larger than the denominator ( the bottom part of the fraction)

• Example one: 12/10 is an improper fraction because the numerator is bigger than the denominator.

• Example two: 6/5 is an improper fraction because he numerator is bigger than the denominator

Least common denominator
