In a district,the ratio of adults to children is 5 : 3.If there are 4 800 children,how many adults are there?

Answer 1

Answer:

8000

Step-by-step explanation:

Basically you want a number to multiply the number of kids by to get adults.  So what number can you multiply 3 by to get 5?  5/3.  So now any number of kids, if you multiply it by 5/3 you wll get the number of adults.  This is how proportions work.

so 4800 kids means there are 5/3 * 4800 adults or 8000 adults.  

Another way to look at it is how much do you multiply 3 by to get 4800.  Whatever that number is you also multiply 5 by to find the corresponding number of adults.  4800/3 = 1600, 5*1600 = 8000
