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

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

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones
