98/980 = 10%
A value like 98/980, or 10%, can show up in everyday life as a discount, a test score, or a portion of a group. For example, 10% off a $50 purchase means the discount is a noticeable but fairly small part of the original price.
You can picture 10% as one part out of ten equal parts, like 1 slice of a pizza cut into 10 slices. A quick estimate is to think of it as about one person in every group of 10, or about 10 items in a group of 100.
A common mistake is thinking that 10% means 10 points or 10 whole items in every situation. The actual amount depends on the total, so 10% of 20 is much smaller than 10% of 1,000.
