Final answer:
The expression 501 % 100 evaluates to 1, with the % operator signifying the modulo or remainder operator in programming, not the mathematical concept of percent.
Step-by-step explanation:
The statement 501 % 100 evaluates to 1. The % operator is called the modulo or the remainder operator in programming, and it gives the remainder of the division of the first number by the second number. Thus, when 501 is divided by 100, the quotient is 5 and the remainder, which is what the modulo operation provides, is 1.
A percent in mathematics typically is a ratio whose denominator is 100, signified by the symbol %. A common example is expressing 5 out of 100 as 5%, where the percentage is calculated as a hundred times the part divided by the total.
However, in the context of programming languages or operations like 501 % 100, the % symbol represents the modulo operation, not the mathematical concept of percent.
