Flock x flock y flock z total pieces of food eaten (from previous page) 123 99 78 food percentage*  %  %  % simulated number of birds in flock for 2nd generation** * divide each flock's 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).

Number of birds in flock X = 12 , Food percentage = 41%

Number of birds in flock y = 10 , Food percentage = 33%

Number of birds in Flock z = 8 , Food percentage = 26%

Using the given data:

Total pieces of food eaten by each flock :

Flock x = 123

Flock y = 99

Flock z = 78

Total pieces of food eaten  = 300

Total number of birds = 30

Next step : Calculate percentage of each flocks' total pieces of food to determine the number and percentage of birds in each flock

Flock X = ( 123 / 300 ) * 100 = 41 %

∴ number of birds in Flock A = 41% * 30 = 12 birds

Flock Y = ( 99 / 300 ) * 100 = 33%

∴ number of birds in Flock Y = 10

Flock Z = ( 78 / 300 ) * 100 = 26%

number of birds in flock Z = 26% * 30 = 8 birds

Hence we can conclude that Number of birds in flock X = 12 , Food percentage = 41%, Number of birds in flock y = 10 , Food percentage = 33%, Number of birds in Flock z = 8 , Food percentage = 26%

Explanation:

All you really need to do is follow the instructions.

Here is the information given:

               Total pieces of

                Food Eaten            Percentage(%)                             Number of birds      

Flock X              123             123/300 = 0.41 x 100% = 41%          0.41 x 30 = 12

Flock Y               99              99/300 = 0.33 x 100% = 33%        0.33 x 30 = 10

Flock Z               78              78/300 = 0.26 x 100% = 26%        0.26 x 30 = 8  

Total                 300                                                    100%                           30

In the percentage portion you need to multiply it by 100% if you want to get the percentage in percent. By multiplying it by the total number of birds, you will be able to get the number of birds in each flock.
