Jessica lost some of her money. She found 3/6 of it. What fraction of her money is still missing?

So you are trying to find out what money was lost. So you have 3/6. This is a fraction that can be reduced. So lets reduce using three.

3/6 divided by 3/3 equals 1/2.

So you have 1/2 of your money. That means you are still missing 1/2.

3/6 is the same as 1/2 so Jessica is missing the other half of it.

She is missing 1/2
