Given:
- 20 balloons
- Ratio of division: 2:3 (Amit:Anshu)

To Find:
- Number of balloons received by Amit and Anshu

Solution:
To divide the balloons in the given ratio, we need to follow the steps below:

Step 1: Find the total number of parts
- The ratio of division is 2:3, which means there are a total of 2 + 3 = 5 parts.

Step 2: Determine the value of one part
- To find the value of one part, we divide the total number of balloons by the total number of parts.
- Therefore, one part is equal to 20 balloons ÷ 5 parts = 4 balloons.

Step 3: Distribute the balloons according to the ratio
- Amit receives 2 parts, which is equal to 2 parts × 4 balloons/part = 8 balloons.
- Anshu receives 3 parts, which is equal to 3 parts × 4 balloons/part = 12 balloons.

Answer:
- Amit receives 8 balloons.
- Anshu receives 12 balloons.

Proportion:
- The concept of proportion is used in this problem to divide the 20 balloons in a specific ratio.
- Proportion is a comparison between two ratios or fractions that are equal to each other.
- In this case, the ratio 2:3 represents the proportion between the number of balloons received by Amit and Anshu.
- By dividing the balloons into 5 equal parts (2 + 3), we ensure that the ratio is maintained and the balloons are distributed according to the given proportion.

Let the no of ballons be x
2x + 3x = 20
5x = 20
x = 4

amit = 8
anshu = 12
