To determine which numbers are between Points A and B on the number line, we first need to identify the numerical values of these points:

  • Point A is at \(-0.8\) (or \(-\frac{8}{10}\)).
  • Point B is at \(-0.2\) (or \(-\frac{2}{10}\)).

Next, we need to check which numbers fall between \(-0.8\) and \(-0.2\). The range of numbers that qualify as being between the two points must be greater than \(-0.8\) and less than \(-0.2\).

Now let’s analyze the options provided:

  1. Negative \(\frac{7}{10}\): This equals \(-0.7\), which is between \(-0.8\) and \(-0.2\).
  2. Negative \(\frac{9}{10}\): This equals \(-0.9\), which is not between \(-0.8\) and \(-0.2\).
  3. Negative one-half (\(-0.5\)): This is between \(-0.8\) and \(-0.2\).
  4. Negative one-fourth (\(-0.25\)): This is also between \(-0.8\) and \(-0.2\).
  5. Negative two-fifths (\(-0.4\)): This is between \(-0.8\) and \(-0.2\).

Thus, the numbers that fall between Points A and B are:

  • Negative \(\frac{7}{10}\) (yes)
  • Negative one-half (yes)
  • Negative one-fourth (yes)
  • Negative two-fifths (yes)

The only number that does not fall between these two points is Negative \(\frac{9}{10}\).

So, the correct answers are:

  • Negative \(\frac{7}{10}\)
  • Negative one-half
  • Negative one-fourth
  • Negative two-fifths
