how do I share $12,000 among three friends in the ratio of 1: 2: 5:
1:2:5 is the same as x:2x:5x
------
Equation:
x + 2x + 5x = 12000
8x = 12000
----------------
x = 1500
2x = 3000
5x = 7500
----------------

Say we have 3 friends: A, B, C

A:B:C = 1:2:5 which means

Friend A has 1x dollars
Friend B has 2x dollars
Friend C has 5x dollars

for some unknown number x. The sum must add to $12,000, which means

1x+2x+5x = 12000

8x = 12000

x = 12000/8

x = 1500

-------------------------------------------------------

1x = 1*1500 = 1500

2x = 2*1500 = 3000

5x = 5*1500 = 7500

-------------------------------------------------------

Friend A gets $1,500

Friend B gets $3,000

Friend C gets $7,500

Check: 1500+3000+7500 = 12000
