Math Problem Statement

Order the numbers from smallest to largest:

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

Solution

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

  1. (1.1)base 2(1.1)_{\text{base } 2}:
  • The integer part "1" in base 2 is 1×20=11 \times 2^0 = 1.
  • The decimal part ".1" in base 2 is 1×21=0.51 \times 2^{-1} = 0.5.
  • So, (1.1)base 2=1+0.5=1.5(1.1)_{\text{base } 2} = 1 + 0.5 = 1.5 in base 10.
  1. (1.4)base 10(1.4)_{\text{base } 10} is already in base 10, so it stays 1.41.4.

  2. (1.5)base 16(1.5)_{\text{base } 16}:

  • The integer part "1" in base 16 is 1×160=11 \times 16^0 = 1.
  • The decimal part ".5" in base 16 is 5×161=5×116=0.31255 \times 16^{-1} = 5 \times \frac{1}{16} = 0.3125.
  • So, (1.5)base 16=1+0.3125=1.3125(1.5)_{\text{base } 16} = 1 + 0.3125 = 1.3125 in base 10.

Now, the numbers in base 10 are:

  • 1.51.5 (from (1.1)base 2(1.1)_{\text{base } 2})
  • 1.41.4 (from (1.4)base 10(1.4)_{\text{base } 10})
  • 1.31251.3125 (from (1.5)base 16(1.5)_{\text{base } 16})

Ordering them from smallest to largest: (1.5)base 16=1.3125<(1.4)base 10=1.4<(1.1)base 2=1.5(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)base 16,(1.4)base 10,(1.1)base 2(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 1×211 \times 2^{-1}).
