Anumber line is drawn left to right with integers spaced 1 centimeter apart. an ant crawls onto the number line at +3. it then crawls 1.5 centimeters left, 4.9 centimeters right, and 7.6 centimeters left. where is the ant on the number line now?

-1.2 cm

Step-by-step explanation:

Let's figure out where the ant is after each step.

Step 1

Start at      +3.0

Move left   - 1.5

Now at       +1.5

Step  2

Start at           +1.5

Move right   + 4.9

Now at         +6.4

Step 3

Start at      +6.4

Move left - 7.6

Now at      -1.2

The ant is now at -1.2 cm.
