30/102 = ≈29.41%
Rounded to 2 decimal places.
A fraction like 30/102 can show up when 30 out of 102 people, items, or survey responses fit a certain category. For example, it could represent the share of students who ride the bus, customers who choose a product, or homes in a neighborhood with a certain feature. That is about 29.41%.
To picture it quickly, think of 30 out of every 100, or just under three out of ten. On a bar or pie chart, it would take up a little less than one-third of the whole.
A common mistake is to treat 30/102 as exactly 30%, since the numerator is 30. The denominator is slightly more than 100, so the actual percentage is a little below 30%.
