The grid provided is 10 x 10. So, because the oil is 40% of the liquid in the recipe, you should shade 40 / 100 squares of the grid to represent the 40%.
To find the number of cups of liquid that are not vegetable oil, we can set up a proportion.
40 / 100 = 10 / x
1000 = 40x
x = 25
There are 25 cups of total liquid in the recipe.
Hope this helps!! :)
