Addition and Subtraction

1) Boni is Planning a Trip to Darjeeling and Digha in the Monsoon. For That Trip, She Was Checking the Average Rainfall for Both Places on Google.

Then Find the Difference Between the Average Rainfall of the Two Cities.

The average rainfall in Darjeeling is 2796 mm
Average rainfall in Digha = 1192 mm
The difference between rainfall is

       

So, the average rainfall difference between Darjeeling and Digha is 1604 mm.

2) Rabi is Planning a Trip to Siliguri and Behrampore in the Monsoon. She Checks the Average Rainfall for Both Places on Google. Between Two Cities, in Which City Does the Most Rainfall Occur?

Then Represent the Difference as a Combination of the Miter, Decimeter, Centimeter, and Millimeter.

Part 1:

The average rainfall in Siliguri is 2651 mm.
Average rainfall in Behrampore = 1036 mm.
we know 2651 > 1036
So, Siliguri receives higher rainfall than Behrampore.
Now, the difference is of rainfall is

Part 2:

We know that 1000 mm = 1 m
100 mm = 1 dm
10 mm = 1 cm
Now, 1615 mm
= 1000 mm + 600 mm + 10 mm + 5 mm
= 1 m + 6 dm + 1 cm + 5 mm
