Answer

Explanation:

Step1: Analyze piano weight

A piano is a heavy - object. $5.5\times10^{2}=550$. Kilograms is a reasonable unit for a piano's weight.

Step2: Analyze salt grain weight

A grain of salt is very light. $1.02\times10^{-3} = 0.00102$. Grams are too large, milligrams are a more appropriate unit for a grain of salt's weight.

Step3: Analyze tractor - trailer weight

A tractor - trailer is a very heavy vehicle. $8.8\times10^{1}=88$. Tons are a suitable unit for its weight.

Answer:

  1. kilograms
  2. milligrams
  3. tons
