Full Answer
C.1/5✓ Correct
The correct answer is C. Total students in Group A = 11 + 3 + 1 = 15. Number who saw a duck = 3. The fraction is 3/15, which simplifies to 1/5.
To find the fraction, we first need the total number of participants in Group A. From the table, this is 11 (Rabbit) + 3 (Duck) + 1 (Other) = 15. The number of participants in this group who saw a duck is 3. Therefore, the fraction is 3/15. This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3. 3 ÷ 3 = 1, and 15 ÷ 3 = 5. So, the simplified fraction is 1/5.
Common mistakes
Forgetting to calculate the total number of participants and using an incorrect denominator. Not simplifying the fraction correctly.
