If 40% of jenne's friends play kickball on weekends,what fraction of her friends don't play kickball?

40% as a fraction is 40/100. Simplify it to 4/10. You can simplify that to 2/5.

1 stands for all her friends.
If 2/5 play, then you can subtract 2/5 from 1 to find out what fraction of her friends don't play kickball.
1-2/5= ______
That is your answer.
