To determine the number of units represented by each tick mark, we need to find the distance between two consecutive integer values and divide it by the number of tick marks between them.
In this case, the distance between two consecutive integer values is 1 (since we are dealing with integer values).
Since there are 4 tick marks between the integer values, the total number of units represented by the tick marks is 1/4.
Therefore, each tick mark represents 1/4 of a unit.
Brianna wants to determine the sum 1.2+(−1.6) using a number line.
She draws a number line and decides to use 4 tick marks between integer values on the number line.
How many units does a tick mark represent?
