21/35 = 60%
A fraction like 21/35 can show up in everyday life when 21 out of 35 people choose the same option in a survey. That means 60% of the group picked it, which could describe students who prefer a certain lunch, sport, or school event.
To picture 21/35 quickly, imagine a group divided into five equal parts. About three of those five parts are included, so it is a little more than half but clearly less than three-quarters.
A common mistake is thinking that 21/35 means 21 out of 100, since percentages are often written with 100 as the denominator. The denominator tells you the total number of parts, so here the whole group has 35 parts, not 100.
