Understanding the Problem

To decrease a number in a given ratio, we need to understand the concept of ratios and proportions. A ratio is a way of comparing two or more numbers by division. In this case, we are given a ratio of 1:3, which means for every 1 unit of the first quantity, there are 3 units of the second quantity.

Decreasing 72 in the Ratio 1:3

To decrease 72 in the ratio 1:3, we need to find the factor by which we need to multiply 72 to get the desired result. Since the ratio is 1:3, we can multiply 72 by 1/3 to get the decreased value.

Calculating the Decreased Value

Let's calculate the decreased value of 72 in the ratio 1:3.

# Import necessary modules
import math
original_value = 72
ratio = 1/3
decreased_value = original_value * ratio
print("The decreased value of 72 in the ratio 1:3 is:", decreased_value)

When we run this code, we get the decreased value of 72 in the ratio 1:3 as 24.

Understanding the Concept of Decreasing in Ratios

Decreasing a number in a given ratio involves finding the factor by which we need to multiply the original number to get the desired result. This factor is determined by the ratio itself. In this case, the ratio is 1:3, which means we need to multiply 72 by 1/3 to get the decreased value.

Real-World Applications of Decreasing in Ratios

Decreasing a number in a given ratio has many real-world applications. For example, in finance, we may need to decrease a certain amount of money in a given ratio to calculate the interest or dividend. In engineering, we may need to decrease a certain value in a given ratio to calculate the stress or strain on a material.

Conclusion

In conclusion, decreasing a number in a given ratio involves finding the factor by which we need to multiply the original number to get the desired result. This factor is determined by the ratio itself. By understanding the concept of decreasing in ratios, we can apply it to various real-world scenarios.
