step 7: determine the sizes of the flocks in the third
generation

• divide each flocks total pieces of food by 300, the total number of pieces of food eaten.

** multiply the food percentage for each flock by the total number of birds (30).

Explanation:

Step1: Calculate Food Percentage

Food Percentage = (Total Pieces of Food Eaten / 300) * 100
For Flock X: $\frac{147}{300}\times100 = 49\%$
For Flock Y: $\frac{93}{300}\times100 = 31\%$
For Flock Z: $\frac{60}{300}\times100 = 20\%$

Step2: Calculate Simulated Number of Birds

Simulated Number of Birds = Food Percentage * 30
For Flock X: $0.49\times30 = 14.7\approx15$
For Flock Y: $0.31\times30 = 9.3\approx9$
For Flock Z: $0.20\times30 = 6$

Answer:

Flock X	Flock Y	Flock Z
15	9	6
