(Smallest goes on top).

• A. 45
• B. 4
• C. 405
• D. 54

Answer 1

$$\begin{array}{ccccc}\text{Number}& \text{45}& \text{4}& \text{405}& \text{54}\\ \text{Number of digits}& \text{2}& \text{1}& \text{3}& \text{2}\end{array}$$ Smallest: 4 (1 digit) and Biggest: 405 (3 digits)
comparing the tens place of 45 and 54: 4 < 5. Thus, 45 < 54
Ascending order: 4, 45,54 and 405
