To determine the distance between −18.26 and −2.45 on a number line, we subtract the smaller number from the larger number.
Distance = |(-2.45) - (-18.26)| = |2.45 + 18.26| = |20.71| = 20.71
So the distance between −18.26 and −2.45 on a number line is 20.71
To determine the distance between −18.26 and −2.45 on a number line, you subtract the smaller number from the larger number.
So, the distance is:
−2.45 − (−18.26)
To subtract a negative number, you can change the subtraction sign to addition and change the sign of the number being subtracted.
−2.45 + 18.26
Now, add the two numbers:
−2.45 + 18.26 = 15.81
Therefore, the distance between −18.26 and −2.45 on a number line is 15.81.
The correct answer is:
15.81
