What does half as many mean?

Answer 1

Half as many means that you have one half less of something.

For example:

"Jack has 10 apples and Peter has half as many as Jack."

So Peter has 5 apples.

But "Half as many again" is not the same. This means an EXTRA half.

"Jack has 10 apples and Peter has half as many again."

This means that Peter has 15 apples.

Answer 2

it depends onn the amount that there is, then take away half, that is half as many
