William has $240 to Michael's $420
this can be written in a ratio as 240 : 420
which can then be reduced to

24:42
12:21
4:7

When you see ratio, think fraction. So, we want :

William's money / Michael's money

They tell us that William has $280 and Michael has $420. Thus,

280 / 420

Now we need to simplify. both 280 and 420 share a factor of 140. Thus,

280/420 = (140 * 2) / (140 * 3) = 140/140 * 2/3 = 1 * 2/3 = 2/3
