Question

Direct and Inverse Variation
Aim: To understand the concept of inverse variation.
Method:
Take a set of sticker dot bindis. Arrange the bindis in six different ways as given
belwo and tabulate:
1) 15 rows and 2 columns
11 10 rows and 3 columns
111) 6 rows and 5 columns
iv) 5 rows and 6 columns
3 rows and 10 columns
vi) 2 rows and 15 columns
Observation:
As the number of rows decreases, the number of columns increases, with the total
number of bindis being constant.
Number of rows 15 10 6 5 3 2.
Number of columns 2 3 5 6 10 15
Total bindis
30 30 30 30 30 30
Conclusion:
An increase or decrease in one quantity result in a corresponding decrease or
increase in the second quantity, such that their product remains constant. The
different arrangements represent inverse variation or inverse proportion.​

Answer 1

Answer:

Direct and Inverse Variation

Aim: To understand the concept of inverse variation.

Method:

Take a set of sticker dot bindis. Arrange the bindis in six different ways as given

belwo and tabulate:

1) 15 rows and 2 columns

11 10 rows and 3 columns

111) 6 rows and 5 columns

iv) 5 rows and 6 columns

3 rows and 10 columns

vi) 2 rows and 15 columns

Observation:

As the number of rows decreases, the number of columns increases, with the total

number of bindis being constant.

Number of rows 15 10 6 5 3 2.

Number of columns 2 3 5 6 10 15

Total bindis

30 30 30 30 30 30

Conclusion:

An increase or decrease in one quantity result in a corresponding decrease or

increase in the second quantity, such that their product remains constant. The

different arrangements represent inverse variation or inverse proportion.
