^ Sounds about right too.

$104,100 p/yr.

There are 52 weeks in a year, so divide by 52.

104,100/52 = 2001.9230769230769231 = $2,001.92 ~ $2,002 p/yr

You are too young to know this, but here goes. They come from storks, obviously.

Thanks Chris

12 is what percent of 25 = 12/25 =  48/100 = 48%

(multiply 12 and 25 by their LCM c;)

11 and 5 are numerators

6 and 12 are denominators

find the lcm of 6 and 12. LCM of 6, 12 = 12 (12*1 = 12, 6*2 = 12)

Convert 5/6 to 5/12, then multiply 5 by 2 also: 10/12

11/12 - 10/12 = 1/12

25%

1 is what percent of 4 = 1/4 = 25/100 = 25%

(4 + 5)(7 - 1) = 4(7-1) + 5(7-1)

This is an example of the distributive property. You can solve if you want, if not, here are the answers c; | :

4 * (7 - 1) = 4 * 6 = 24

5 * (7 - 1) = 5 * 6 = 30

24 + 30 = 54.
