Hi, Since 33^{1}/_{3}% is onethird, 30 is twothirds of the number you started with. Half of twothirds is onethird and half of 30 is 15. Thus 15 is onethird of the number you started with. Three times 15 is 45 and three times onethird is one, hence the number you started with is 45. Let's check. Onethird of 45 is 15 and 45, decreased by 15 is 30. Penny
