To order the numbers \(1 \frac{3}{4}\), \(-1.5\), \(-1.1\), and \(1.03\) on a number line from least to greatest, we first convert all the numbers to decimal form for easier comparison:
- \(1 \frac{3}{4} = 1.75\)
- \(-1.5\) stays \(-1.5\)
- \(-1.1\) stays \(-1.1\)
- \(1.03\) stays \(1.03\)
Now, we will compare the numbers:
- \(-1.5\) (which is the smallest)
- \(-1.1\)
- \(1.03\)
- \(1.75\) (which is the largest)
So the numbers in order from least to greatest are:
\(-1.5, -1.1, 1.03, 1.75\)
