If a national event has 1,200 participants and 15% of them are from abroad, how many participants are from the country? (2022)

Step 1: Find out how many participants are from abroad by calculating 15% of 1,200.
Step 2: To calculate 15% of 1,200, multiply 1,200 by 0.15 (which is the decimal form of 15%).
Step 3: Perform the multiplication: 0.15 * 1,200 = 180. This means there are 180 participants from abroad.
Step 4: To find out how many participants are from the country, subtract the number of participants from abroad (180) from the total number of participants (1,200).
Step 5: Perform the subtraction: 1,200 - 180 = 1,020. This means there are 1,020 participants from the country.
