1. Phil has 21 balloons. He puts the same number of balloons on 3 tables. How many balloons does Phil put on each table?
Answer: Phil puts 7 balloons on each table because 21 divided by 3 equals 7. So, he distributes 7 balloons on each table.
2. Phil has 21 balloons. Then he gives 3 away. How many balloons does Phil have left?
Answer: After giving away 3 balloons, Phil has 18 balloons left because 21 balloons minus 3 equals 18.
3. Phil has 21 balloons. Then Jen gives him 3 more. How many balloons does Phil have now?
Answer: Phil has 24 balloons now because 21 balloons plus 3 equals 24 after receiving 3 more balloons from Jen.
4. Phil has 3 tables with 21 balloons on each. How many balloons does Phil have in all?
Answer: Phil has a total of 63 balloons because each table has 21 balloons, and there are 3 tables, so 21 balloons multiplied by 3 equals 63 balloons in total.
