Where is the real number −1.25 located on the number line?
Answer and explanation
Correct answer: Between −2 and −1
To locate −1.25, compare it with the adjacent integers −2 and −1. Since −2 < −1.25 < −1, the number lies between −2 and −1, so option D is correct. On the number line, −1.25 is 0.75 unit to the right of −2 and 0.25 unit to the left of −1. The negative sign places it to the left of zero, and its magnitude is greater than 1, so it must lie to the left of −1 rather than between −1 and 0. Options A and C are positive intervals and cannot contain a negative number. Option B contains numbers such as −0.5, which are greater than −1, not −1.25.
