Question

You helped organize a birthday party for twenty kids. You filled 150 water balloons and the kids smashed 4/5 of them in ten minutes. How many total balloons are leftover?

Answer 1

30

Explanation:

Okay, to find the number of balloons left over, disregard the number of kids and focus only on 150 balloons and that only 4/5 were "smashed." Multiply 150 by 4/5 to find the amount of balloons used, which is 120, and find the difference between 150 and 120, which is 30.
