Questions & Step-by-Step Solutions

A national event has a total of 500 volunteers. If 20% of them are from local colleges, how many volunteers are from local colleges?
  • Step 1: Understand that we need to find 20% of the total number of volunteers, which is 500.
  • Step 2: Convert the percentage (20%) into a decimal. To do this, divide 20 by 100, which gives us 0.20.
  • Step 3: Multiply the decimal (0.20) by the total number of volunteers (500). So, calculate 0.20 * 500.
  • Step 4: Perform the multiplication: 0.20 * 500 = 100.
  • Step 5: Conclude that there are 100 volunteers from local colleges.
  • Percentage Calculation – Understanding how to calculate a percentage of a total amount.
  • Basic Arithmetic – Applying multiplication to find a portion of a whole.
