What is the decimal equivalent of the fraction 1/1?

The decimal equivalent of the fraction 1/1 is 1.0 because any number divided by itself equals 1, provided the number is not zero. In this case, since both the numerator and denominator are the same (1), the fraction simplifies directly to 1. When expressed in decimal form, this remains 1.0.

Understanding this concept is foundational in mathematics, particularly when dealing with fractions and their decimal representations. Other choices reflect either fractions or percentages that do not correspond to the correct conversion of 1/1. Thus, recognizing that 1/1 directly corresponds to the whole number 1, represented as 1.0 in decimal, solidifies the understanding of basic fraction-to-decimal conversions.
