1 Picture This! Multiply Fractions by drawing arrays

2 1 1 1 x 1 looks like this:

3 1 1212 1212 x 1 looks like this:

4 Half of 50 ¢ is 25 ¢ Half of a half is a quarter x looks like this: 1212 1212 1212 1212 Half of $1 is 50 ¢

5 3535 1212 Here’s x 3535 1212 x= 3 10

6 The denominators tell the array’s dimensions 1212 3535 2 x 5 array x

7 The numerators tell you how many to color in 3535 1212 3 x 1 = 3 x

8 The answer is the number of colored rectangles over the total number of rectangles 3535 1212 x= 3 10

9 3 colored rectangles in a 5 x 2 array is 3 out of 10 or 3535 1212 x= 3 10 3 10
