To order the numbers on the number line, we first convert them into decimal form if necessary:
- \( 1 \frac{3}{4} = 1 + 0.75 = 1.75 \)
- \( -1.5 \) (already in decimal form)
- \( -1.1 \) (already in decimal form)
- \( 1.03 \) (already in decimal form)
Now, we can compare the values:
- \( -1.5 \)
- \( -1.1 \)
- \( 1.03 \)
- \( 1.75 \)
Placing them in order from least to greatest, we have:
- \( -1.5 \)
- \( -1.1 \)
- \( 1.03 \)
- \( 1.75 \)
Thus, the correct order is:
A. -1.5, B. -1.1, C. 1.03, D. 1.75.
