  1. Numbers 1 2 and 4 7 Fractions We have been working with familiar fractions like But what about a fraction where the top number, the numerator, is more than the lower number, the denominator?

  2. Numbers 15 5 This is called an Improper Fraction Fractions Take this fraction What does it mean? With the fraction 4 7 it means that there are “4 of 7”

  3. Numbers 5+5+5 = of 5 15 5 Fractions This fraction says that there are: there are 3 lots of 5 in the 15 (3x5=15) 15 5 3 =

  4. Numbers 18 6 3 = Fractions Lets look at a few examples to be sure we understand this: How many times does 6 go into 18? 22 11 2 = How many times does 11 go into 22?

  5. Numbers 19 6 3 1 6 = Fractions But what happens when the denominator does not divide into the numerator evenly? How many times does 6 go into 19? How many remainders are there? 27 11 5 11 2 = How many times does 11 go into 27? How many remainders are there?

  6. Numbers can be turned into 6ths by multiplying 3 by 6 (18) and placing this on top of 6 Fractions We have been turning Improper Fractions into Mixed Fractions. How do we do the reverse? 3 3 x 6 = 18 6

  7. Numbers can be turned into 7ths by multiplying 2 by 7 (14) and adding this to the 3 = 3 7 2 17 7 Fractions Look at these examples: can be turned into 3rds by multiplying 4 by 3 (12) and adding this to the 2 = 2 3 4 14 3
