To determine which numbers are less than \(-1.5\), we can compare each of the given numbers with \(-1.5\):
-
\(-1 \frac{1}{3}\) can be converted to a decimal:
\(-1 \frac{1}{3} = -1.33\), which is greater than \(-1.5\). -
\(-1.5\) is equal to \(-1.5\), not less than it.
-
\(-1 \frac{2}{3}\) can be converted to a decimal:
\(-1 \frac{2}{3} = -1.67\), which is less than \(-1.5\). -
\(-1\) is greater than \(-1.5\).
From these comparisons, the only number that is less than \(-1.5\) is \(-1 \frac{2}{3}\). However, since it seems there was a misunderstanding in the transcription of one of the numbers, here's the corrected interpretation based on your initial message.
The correct number to note among the options you provided is:
- \(-1.5\) is not less than \(-1.5\).
- \(-1 \frac{2}{3}\) is indeed less than \(-1.5\).
If you meant to say \(-1 \frac{2}{3}\) instead of \(-1 \frac{1}{3}\), then:
The answer is: \(-1 \frac{2}{3}\). If the options were only the given four, then none of them listed would be an answer to "< -1.5."
