write a ratio and percent for the shaded area
42/100 = 42%
To find the ratio and percent for a shaded area, you need to know the total area and the area of the shaded region. Here's how you can calculate it:
1. Determine the total area: Measure the entire region that contains the shaded area and determine its area. Let's say the total area is 100 square units.
2. Determine the area of the shaded region: Measure the shaded region and find its area. Let's say the shaded area is 25 square units.
3. Calculate the ratio: The ratio compares the area of the shaded region to the total area. In this case, the ratio would be 25:100 since the shaded area is 25 square units and the total area is 100 square units.
4. Calculate the percent: To determine the percent, divide the area of the shaded region by the total area and multiply by 100. In this case, (25 / 100) * 100 = 25%. Therefore, the shaded area represents 25% of the total area.
So, the ratio for the shaded area is 25:100, and the percent is 25%.
