beth is decorating 24 cards. she decorated 1/3 of the cards on thursday and 1/2 of the cards on friday. What part of the cards does beth still need to decorate?

24 divide by 1/3 is 8 cards on thursday, 24-8=16 remaining cards

16 divide 1/2 is 8 cards on friday, 16-8=8 cards remaining

I don't know how to do from here, please help me, thank you.

The problem says that she decorated 1/2 of the cards on Friday. That means she decorated 12 on Friday.

12 + 8 = 20

24-20 = 4

4/24 - 1/6 she still needs to decorate.
