Between them, three brothers -Michael, Daniel and Nicholas - eat 2/3 of a pie. If Michael eats 1/4 the amount eaten and Daniel eats 1/5 of what Nicholas eats, what fraction of the pie does Nicholas eat?
Can someone start me off in the right direction. What I have to start is (1/4)(2/3)-(1/5)(1/4)(2/3)-x=0. This is clearly not the correct equation. What am I doing wrong?
