How many of shapes must be shaded so that 2/5 of the figure is unshaded
um, 3/5 of them, however many that is ...
To determine the number of shapes that must be shaded so that 2/5 of the figure is unshaded, we need to understand the concept of shading fractions of a figure.
1. Start by visualizing the entire figure. This could be a shape, such as a rectangle, composed of smaller shapes or sections.
2. Remember that the term "2/5" refers to two parts out of five equal parts. This means, ideally, 2/5 of the figure should be unshaded, while the remaining 3/5 should be shaded.
3. Divide the figure into five equal parts, either mentally or by drawing lines to create sections. Each part represents 1/5 of the entire figure.
4. Begin shading the sections starting from left to right. Shade the first three sections to achieve the 3/5 shaded or 2/5 unshaded condition.
Therefore, to have 2/5 of the figure unshaded, you need to shade three out of the five sections.
