Hint:
We are given one quantity in a certain unit. And we are asked to convert the quantity in another unit. The given quantity is 20 dekagrams. We are asked to find how much it measures in kilogram. For this question, we should know how to convert different units.
The correct answer is: 0.2
The given quantity is 20 dekagrams.
We are asked to convert the above quantity in kg.
To convert the above quantity in kg, we should know the relation between them.
1 dekagram = 0.01 kilogram.
Kilogram is larger than dekagram and when we have to convert some smaller unit into larger unit, we get decimal points.
So, to convert 20 dekagrams into kg we will multiply the value by 0.01
We get
20 dekagrams = 20 × 0.01 kg
= 0.2 kg
So, the value of given quantity in kg is 0.2kg.
For such questions, we should know about the different units and relation between them.
