A fraction like 270/690 can show up when 270 people out of 690 surveyed choose the same answer, or when 270 items out of a shipment of 690 are sold. This means the group represents about 39.13% of the total.
To picture 270/690 quickly, think of it as a little less than 4 out of every 10 parts. It is also close to two-fifths, so you can estimate it as roughly 40% without needing the exact value.
A common mistake is to think 270/690 is closer to one-half just because both numbers are fairly large. The important comparison is between the numerator and denominator: 270 is clearly less than half of 690, so the percentage should be below 50%.
