420/1050 = 40%
A value like 420/1050, or 40%, can show up in everyday situations such as a sale where an item is marked down by 40%. It could also describe survey results, test scores, or the portion of a group that prefers a certain choice.
You can picture 40% as four out of every ten equal parts, or a little less than half of something. On a 100-square grid, it would fill 40 squares, making it easy to estimate at a glance.
A common mistake is thinking 40% is close to three-quarters because the numbers 420 and 1050 look fairly large. It is actually less than half, so the fraction should represent a smaller portion of the whole.
