30/42 = ≈71.43%
Rounded to 2 decimal places.
A value like 71.43% could describe how many of 42 questions someone answered correctly: 30 correct answers is a little over seven out of every ten. The same kind of share can show up in survey results, attendance, or items finished on a checklist.
To picture it quickly, imagine 10 equal sections with about 7 filled in, plus a small bit more. That’s close enough for a quick estimate without focusing on the exact decimal.
A common mistake is to forget what the percentage is measured against. Here, the 30 is part of a group of 42, so it doesn’t mean 30 out of 100.
