Annie was given a pack of crayons. The pack contained 21 crayons. She already had a box of 36 crayons in her locker. Her friend Bobby gave her half the amount she already had in her locker. She decided to give her sister Mary 1/3 of her total amount of crayons. How many crayons does she give to Mary?
Annie starts with 21 + 36 = <<21+36=57>>57 crayons.
Bobby ends up giving her 36 / 2 = <<36/2=18>>18 crayons.
Annie now has a total of 57 + 18 = <<57+18=75>>75 crayons.
She ends up giving Mary a total of 75 * (1 / 3) = <<75*(1/3)=25>>25 crayons.
