Happy Third Week of Summer!
A little trickier is fraction of an amount. To find the fraction of an amount we have to remember that the fraction line also means division. So what is 1/4 of 20? It is 20 divided by 4 which is 5. To show this in pictures, you would draw 20 circles or x's and put them into 4 groups (quarters). How many in each group? There would be 5.
