Draw rectangles and find the product of 1 2 and 1 4 .

To start with, let's draw a rectangle and divide it into four equal parts. Next, we draw a horizontal line to divide one of these rectangles into two equal parts. Each of these small rectangles is 1 2 of 1 4 of the largest rectangle. That is, 1 2 × 1 4 of it. Let us extend the horizontal lines. Thus, 1 2 × 1 4 = 1 8 .

Draw rectangles and find the product of 1 3 and 1 6 .

To start with, let's draw a rectangle and divide it into six equal parts. Next, we draw horizontal lines to divide one of these rectangles into three equal parts. Each of these small rectangles is 1 3 of 1 6 of the largest rectangle. That is, 1 3 × 1 6 of it. Let us extend the horizontal lines. Thus, 1 3 × 1 6 = 1 18 .

Draw rectangles and find the product of 1 5 and 1 8 .

To start with, let's draw a rectangle and divide it into eight equal parts. Next, we draw horizontal lines to divide one of these rectangles into five equal parts. Each of these small rectangles is 1 5 of 1 8 of the largest rectangle. That is, 1 5 × 1 8 of it. Let us extend the horizontal lines. Thus, 1 5 × 1 8 = 1 40 .
