42/137 = ≈30.66%
Rounded to 2 decimal places.
A value like 42/137, or about 30.66%, could describe 42 students out of 137 choosing a certain lunch, team, or school activity. It might also represent the share of survey respondents who prefer one option.
You can picture it as just under one-third of a group, since one-third is about 33.3%. In a group of 100 people, it would look like roughly 31 people, which makes the size easier to estimate quickly.
A common mistake is treating 42/137 as if it were close to 42%, because the numerator is 42. The denominator matters just as much: 42 out of 137 is much less than 42 out of 100.
