Question

one kilogram is about 2.205 pounds. When a 55 gallon aquarium is filled, it weights 625 lb. to the nearest tenth, how many kilograms os this

Answer 1

If you know 1 Kg = 2.205 lbs. This is represented as

\[\frac{ 1 Kg }{ 2.205 lbs }\]

So to get Kg from a known lbs you can write this as:

\[\frac{ 1 kg }{ 2.205 lbs } *\frac{ 625lbs }{ 1 kg } ==\frac{ 625 lbs }{ 2.205 lbs } = x \]
