Ruth’s brother, Ethan, planted a garden for her as a surprise while she was away. He planted seeds for vegetables in of the garden. He also planted flowers and herbs.

The entire circle in the graph at right represents the area of Ruth’s garden. If the lightly shaded portion represents flowers, estimate what percentage of the garden could be herbs. Explain your estimate.

A circle is divided in half vertically. The right side is labeled 50% vegetables. The left side is divided into two unequal sections with the larger section shaded lightly and the smaller section shaded dark.

Because the circle in the graph above represents the entire garden, the circle also represents . Now can you tell how much the two shaded portions of the graph represent together?

The semicircle below represents of the garden Ethan planted for Ruth. If the blue line segment divides the section in half, each resulting half is of the entire garden. Can this help you estimate the percentage that the dark portion represents?

A semicircle to represent 50% of the garden Ethan planted for Ruth. If you divide the semi circle in half you get two sections of 25%. One of the unknown sections appear to be half of a quarter.

The darkly shaded portion appears to be about of the circle. It is about one fourth of the remaining , so the garden was planted with about herbs.
