40000 people visited the Emirates Park Zoo in Abu Dhabi last Year. Ratio of number of visitors of children to women to men is 4: 7: 9. Find the number of children, women and men who visited the zoo.

40000 total visitors

Step-by-step explanation:

Let p represent a multiplier. Then the total number of visitors to the park is

4p + 7p + 9p = 40000.

This simplifies to 20p = 40000, so that p = 2000.

Then the number of children who visited is 4p = 8000; the number of women is 7p = 14000, and the number of men is 9p = 18000.

Summing up these results gives us the total number of chidren, women and men who visited the zoo last year: 8000 + 14000 + 18000, or 40000.

The correct answer is: Additive identity property

Explanation:
Additive identity property says that if zero is added to any real number, the resultant would be the same real number.

For Example:
6+0 = 6
 
In this case, we have added zero to a real number (6) and got that same real number (6) in return.
