Correct. They have, in total, 1/3lbs of cake. To divide that equally to three people, we divide 1/3 by 3, or multiply 1/3 by 1/3, and get 1/9lbs per person.

Gavin is correct.

  • Divide 1/3 by 3
  • Multiply 1/3 by 1/3
  • Each friend gets 1/9

Total pound of cake = 1/3

Numbwr of friends = 3

  • Since the cake is to be shared equally :

  • Pound of cake ÷ Number of friends = 1/3 ÷ 3

  • Take the reciprocal of 3 ; gives 1/3 and use the multiplication operation

  • Pound of cake × 1/3 = 1/3 × 1/3

  • 1/3 × 1/3 = 1/9

Hence, each friend gets 1/9 pounds.
