Answer:
If Lawrence has 24 beads and divided them into 4 groups you want to see how many he put into each group first
To do this we are going to take 24/4=6
Each group has 6 in it
If he gave one group to his sister, than he gave 6 beads to his sister
Now we want to take 6 away from 24 to find out how many he has left
24-6=18
He now has 18 beads
Hope this helps ;)
