Q: During a national event, if 70% of the attendees are adults and there are 350 attendees, how many are children?
Solution:
Number of adults = 70% of 350 = 0.70 * 350 = 245. Number of children = 350 - 245 = 105.
Steps: 5
Show Steps
Step 1: Identify the total number of attendees, which is 350.
Step 2: Calculate the number of adults by finding 70% of 350. This is done by multiplying 0.70 by 350.
Step 3: Perform the multiplication: 0.70 * 350 = 245. This means there are 245 adults.
Step 4: To find the number of children, subtract the number of adults from the total number of attendees: 350 - 245.
Step 5: Perform the subtraction: 350 - 245 = 105. This means there are 105 children.
