Improper Fractions

• If the numerator is larger than the denominator, it is called an improper fraction (it is more than one)

• 6/5 = 1/5 + 1/5 + 1/5 + 1/5 + 1/5 + 1/5

• It takes 5 to get to the whole, one more past the whole (greater than 1)

• 1 1/5

Improper Fractions

• 4/3 is improper because the numerator is larger than the denominator ( it is more than 1)

• 1/3 + 1/3 + 1/3 + 1/3 = 4/3

• it takes 3 to get to 1 whole, and 1 more = 1 1/3

•
