To find the positive and negative difference between -11.9 and 2.8, we need to subtract the two numbers in both directions.Positive difference: To find the positive difference, we subtract the smaller number from the larger number. In this case, 2.8 is larger than -11.9, so we subtract -11.9 from 2.8:
2.8 - (-11.9) = 2.8 + 11.9 = 14.7
Therefore, the positive difference between -11.9 and 2.8 is 14.7.Negative difference: To find the negative difference, we subtract the larger number from the smaller number. In this case, -11.9 is smaller than 2.8, so we subtract 2.8 from -11.9:
-11.9 - 2.8 = -14.7
Therefore, the negative difference between -11.9 and 2.8 is 14.7.
