What is The 100% rule?

The 100% rule is like having a special toy box that tells you exactly how many toys you can add or take away without breaking the balance inside.

Imagine your favorite toy box has exactly 10 toys in it, that’s its perfect number. Now, if you want to add more toys, you can do so only up to the point where you still have at least 10% of the original amount left. That means you could add up to 9 more toys (because 10 + 9 = 19), and then take away 1 toy again, but if you go over that, like adding 10 more, it feels a bit too full.

Or, if you want to take some toys out, you can only take as many as 10% of the original amount, which is 1 toy. So you could take one toy out and still keep your box happy.

It’s like having a little rule that helps your toy box stay balanced, not too full, not too empty.

Why it's called the 100% rule

The name “100% rule” comes from the original number of toys (which is 100%), and the rule says you can’t change more than 10% of that original amount without messing up the balance. So, whether you’re adding or taking away, it’s like having a little helper who makes sure everything stays just right!

Examples

  1. A group of kids share 10 cookies. If one kid gets 2 more, the others get 2 less, that's like The 100% rule.
  2. Imagine a jar with 10 marbles; if you take 1 away, another one is added, this follows The 100% rule.
  3. If a class of 20 students loses 5, then the rest have to cover their share, that’s similar to The 100% rule.
