It may or may not be the correct answer. I'm only trying to help.
1*10<span>- 3 is the standard form of 0.001</span>
This can be solve by 3 variable equation
let x be the money of luke
y money of rachel
z money of daniel
first equation
x = y + 21
second equation
x = z + 48
third equation
x + y + z = 168
solving simultaneously
x =79
y = 58
z = 31
The greatest common factor between 72 and 54 is 18.
