Final answer:
To represent the given numbers on the number line, we need to understand what each number represents and their approximations. The correct representation on the number line is [3, 1.732, 0.714, -2.5, 0.75, 2.236, 3.143], which corresponds to option c).
Step-by-step explanation:
To represent the given numbers on the number line, we first need to understand what each number represents. The square root of 9 is 3, the square root of 3 is approximately 1.732, 5/7 is approximately 0.714, -2 1/2 is -2.5, 0.75 is 0.75, the square root of 5 is approximately 2.236, and π (pi) is approximately 3.143 or 22/7.
This means that the correct representation of the numbers on the number line would be [3, 1.732, 0.714, -2.5, 0.75, 2.236, 3.143], which corresponds to option c).
