Hint:
We are given a table with columns denoting different units of length. There are four rows, with some value in certain column. We are just asked the question related to second row. We have to write the quantity given in second row in dekameters. We don’t have to pay attention to other rows.
The correct answer is: 0.47
The quantity given in second row is 47 decimeters.
We are asked the above quantity in dekameters.
To convert the above quantity in dekameters, we should know the relation between them.
1 decimeters = 0.01 dekameters.
So, to convert 47 decimeters into dekameters we will multiply the value by 0.01
We get
47 decimeters = 47 × 0.01
= 0.47 dekameter.
So, the value given in the second row in dekameters is 0.47.
For such questions, we should know about the conversion of different units.
