Question

Which description most accurately describes the motions for the calculation -2.48-(-6.1) ?

a. A small movement to the left followed by a large movement to the right.
b. A large movement to the left followed by a small movement to the left.
c. A large movement to the left followed by a small movement to the right.
d. A small movement to the left followed by a large movement to the left

Answer 1

The motion described in the calculation -2.48-(-6.1) can be thought of as a small movement to the left followed by a large movement to the right.

Step-by-step explanation:

The motion described in the calculation -2.48-(-6.1) can be thought of as a small movement to the left followed by a large movement to the right. When subtracting a negative number, it is equivalent to adding a positive number. So, the calculation can be rewritten as -2.48 + 6.1. Starting from -2.48 on a number line, we move 6.1 units to the right to reach the final answer of 3.62. Therefore, the correct description is option a, a small movement to the left followed by a large movement to the right.
