Finding fractions of a number

For both levels 1 and 2, all you'll have to do with fractions is find fractions of a number.

For example, you may be asked to find 1/4 of something.

To do this, simply divide by 4.

Or you might be asked to find 2/5 of something.

To do this, divide by 5 then times by 2.

In short:

To find a fraction of a number, divide by the bottom number and multiply by the top number.

And that's it!
