20/64 = 31.25%
A value like 20/64, or 31.25%, can show up in everyday life when 20 out of 64 seats are filled, a survey gets 20 responses from 64 people, or a game is completed 20 parts out of 64. It represents a little less than one-third of the total.
To picture 20/64 quickly, imagine a group divided into four equal parts. One-fourth is 25%, so 20/64 is slightly more than one-fourth; it is also close to 30%, but a little higher.
A common mistake is thinking that 20/64 is close to 20% because the numerator is 20. The denominator matters because it tells you the size of the whole, so 20 out of 64 is quite different from 20 out of 100.
