Answer 1

Hello!

Answer:

Number of birds in the first flock → A=12

Number of birds in the second flock → B=10

Number of birds in the third flock → C=8.

Step-by-step explanation:

The details and instructions are already given. So, let's mark birds in flock by letters A, B, and C.

Given:

Total piece of food for each flock: A=123 | B=99 | C=78 → 123+99+78=300, which gives the total number of pieces of food eaten.

Total number of birds: 30

Solution:

1. Divide each flock's total piece of food by 300: A=123/300=0.41

| B=99/300=0.33

| C=78/300=0.26

If you need the percentage in percents(%), just multiply the numbers by 100: A=0.41*100=41% | B=0.33*100=33% | C=0.26*100=26%

2. Multiply percentage by number of birds(30): A=0.41*30=12.3

| B=0.33*30=9.9

| C=0.26*30=7.8

But(!) birds cannot be counted in decimals; therefore, we have to round up the numbers: A=12 | B=10 | C=8. That is how we obtain number of birds in the flock.
