10
In the quinary numeral system, the number five is represented by the digit "10". This system uses five digits: 0, 1, 2, 3, 4. When a number becomes greater than or equal to 5, the next digit place is used, and the digit "10" indicates that there is one five (5 in the decimal system) in that place. To represent numbers greater than 10, corresponding combinations of digits are used; for example, 11 is represented as "12", 12 as "13", and so on.
