Study Notes
- The text is about using area models to represent and solve multiplying fractions problems, specifically fractions times fractions.
- Three-fourths (3/4) and one-third (1/3) are used as examples to demonstrate the area model method.
- To represent three-fourths (3/4), the area is divided into fourths and three sections are shaded, using horizontal lines for distinction.
- One-third (1/3) is represented by dividing the area into thirds and shading one section, using diagonal lines for distinction.
- The answer is found by counting the number of sections that overlap between the two fractions (three sections) and comparing it to the total number of sections in the big square (twelve sections). The answer is simplified to one fourth (1/4).
- Three-fifths (3/5) and two-fourths (2/4) are used as the next example, and the process is repeated with the area divided into fifths and fourths, respectively.
- The answer is found by counting the number of sections that overlap (six sections) and comparing it to the total number of sections in the big square (20 sections).
- The fractions are multiplied straight across (3 × 2 = 6 and 5 × 4 = 20) to check the accuracy of the area model method.
