3/450 = ≈0.67%
Rounded to 2 decimal places.
A value like 3/450, or about 0.67%, can show up when only a few items in a large group have a certain feature. For example, three defective products in a shipment of 450 would represent roughly this share of the total.
To picture it quickly, imagine 450 small squares with only 3 of them shaded. Since 1% of 450 is 4.5 items, 3 items is a little less than 1%, making 0.67% a reasonable estimate.
A common mistake is to think 3/450 is close to 3% because the numerator is 3. The denominator matters just as much, and a large denominator makes the overall fraction much smaller.
