£113  £226  £339 Edit: For a ratio you add the numbers up, 2 + 4 + 6 = 12. there fore 2 twelths of the money goes to one child, 4 twelths to the other and 6 the other. so.... 2/12 times 680 = £113 (roughly. doing this in my head). & 4/12 times 680 = £226 (or you can multiply 113 by 2 as this child is getting twice as much). etc.

Well, I'm bad at math, but I think the simplest way is to think of it as twelve shares total 2 for one person, 4 for another, and 6 for the last kid. divide by 12, and then multiply for each kid. There's probably a more eloquent way to do it with algebra, but hey, this works.

8302017 Get a ruler in your hands. Measure things until you start to understand how a ruler works. Measure some stuff and figure out where the center is. Say you measure a book and it's 7/8" thick. You look at your ruler and see that every eighth is divided into two sixteenths, so obviously half of 7/8" is going to be 7/16". If you write that out you have 1/2 x 7/8 = 7/16. And you notice that 1/2 is divided into 2/4 and then into 4/8 and so on, so you can convert anything to anything by multiplying all the numbers on top and then all the numbers on bottom. Other rulers are divided into 10 and 100 parts. But an inch is still an inch, so anything on one ruler can be translated to the other ruler. A half inch on one ruler is 5/10 or 50/100 on the other. An eighth inch is just 12.5 marks when you have 100 marks per inch. A metric ruler divides an inch into 25.4 parts, so a half inch would be 12.7 of those parts. Pretty simple, isn't it? Practice this a bit and people will think you went to wizard school. ANSWER: 2+4+6=12 so divide your fortune into 12 pars and give 2 to one kid, 4 to another, and 6 to the third kid.
