Questions & Step-by-Step Solutions

A wildlife reserve has 60% of its area as forest and the rest as grassland. If the total area is 300 hectares, how many hectares are grassland?
  • Step 1: Understand that the total area of the wildlife reserve is 300 hectares.
  • Step 2: Know that 60% of the area is forest, which means the rest is grassland.
  • Step 3: Calculate the percentage of the area that is grassland. Since 60% is forest, the grassland is 100% - 60% = 40%.
  • Step 4: Convert the percentage of grassland (40%) into a decimal for calculation. 40% as a decimal is 0.40.
  • Step 5: Multiply the total area (300 hectares) by the decimal for grassland (0.40) to find the area of grassland: 0.40 * 300 = 120 hectares.
  • Step 6: Conclude that there are 120 hectares of grassland in the wildlife reserve.
