1 Dividing Fractions Part 1: Dividing a Whole Number by a Unit Fractions

2 To answer this question start by drawing a model representing the 2 pies. Next divide each pie into fourths.

3 We can use a number sentence to represent our model. division

4 The model shows that: 4 2 x 4= 8 8 8 pieces

5 Let’s Try Another one …

7 The model shows that…. 6 3 x 6 = 18 3 x 6 = 18 18

11 Now think about this….

12 Let’s try another one…

13 Draw a model to represent 7 wholes. Remember when we divide we are asking how many of something is in something else. So, in this question we are asking, ? To solve, start by cutting the each whole into fourths.
