Final answer:
The fraction 2/3, being a positive number less than 1, is located between -1 and 0 on the number line, making option (d) the correct answer.
Step-by-step explanation:
The question is asking to identify the location of the fraction 2/3 between two consecutive integers on a number line. To determine this, we consider that any fraction greater than 0 and less than 1 falls between the numbers 0 and 1 on the number line. Since 2/3 is a positive fraction less than 1, it must be positioned between 0 and 1. Therefore, the correct answer is (d) -1 and 0, as 2/3 is greater than -1 and less than 0.
