Question

Inspired by a video, Brooke decided to try a Filipino chicken. She bought 17 over 21 pounds of chicken, but the recipe required only 10 over 21 pounds, how many pounds of chicken remained unused?

  1. 5 over 21
  2. 1 third
  3. 1 fourth
  4. 2 over 21

hintHint:

simply we have to substract
required chicken - bought chicken

The correct answer is: 1 third


    simply we have to substract
    required chicken - bought chicken
    17 over 21 minus 10 over 21 equals 7 over 21
    The answer can be simplified further by using a common divisor 7.
    7 over 21 divided by 7 over 7 equals 1 third
