438/600 = 73%
A fraction like 438/600 could describe a survey where 438 out of 600 people choose the same answer. It could also represent a test score, the portion of a project completed, or the amount of a product that has sold.
The value is 73%, so you can picture it as a little less than three-quarters of a whole. On a shaded grid of 100 squares, about 73 would be filled, leaving 27 unfilled.
A common mistake is to treat 73% as if it were close to 100% just because it is above 70%. It is a strong majority, but it still leaves more than one-quarter of the total uncovered or unfinished.
