Order the numbers from smallest to largest:

(1.1)base2, (1.4)base10, (1.5)base16 

Let's convert all the given numbers to the same base (base 10) for comparison.

1. \( (1.1)_{\text{base } 2} \):
- The integer part "1" in base 2 is \( 1 \times 2^0 = 1 \).
- The decimal part ".1" in base 2 is \( 1 \times 2^{-1} = 0.5 \).
- So, \( (1.1)_{\text{base } 2} = 1 + 0.5 = 1.5 \) in base 10.

2. \( (1.4)_{\text{base } 10} \) is already in base 10, so it stays \( 1.4 \).

3. \( (1.5)_{\text{base } 16} \):
- The integer part "1" in base 16 is \( 1 \times 16^0 = 1 \).
- The decimal part ".5" in base 16 is \( 5 \times 16^{-1} = 5 \times \frac{1}{16} = 0.3125 \).
- So, \( (1.5)_{\text{base } 16} = 1 + 0.3125 = 1.3125 \) in base 10.

Now, the numbers in base 10 are:
- \( 1.5 \) (from \( (1.1)_{\text{base } 2} \))
- \( 1.4 \) (from \( (1.4)_{\text{base } 10} \))
- \( 1.3125 \) (from \( (1.5)_{\text{base } 16} \))

Ordering them from smallest to largest:
\[ (1.5)_{\text{base } 16} = 1.3125 < (1.4)_{\text{base } 10} = 1.4 < (1.1)_{\text{base } 2} = 1.5 \]

Thus, the order from smallest to largest is:
\[ (1.5)_{\text{base } 16}, (1.4)_{\text{base } 10}, (1.1)_{\text{base } 2} \]

### Tip:
When converting fractional numbers between bases, treat each digit after the decimal point as a power of the base's reciprocal (e.g., in base 2, .1 is \( 1 \times 2^{-1} \)).
