Understanding the Problem

When we are given a ratio, it means that for every 7 units of one quantity, there are 3 units of another quantity. In this case, we are dealing with a financial ratio, where we need to decrease R 1400 in the ratio 7:3. This means that we need to find the amount that should be decreased from R 1400 in order to maintain the ratio of 7:3.

Calculating the Decrease

To calculate the decrease, we need to first find the total number of parts in the ratio, which is 7 + 3 = 10. Then, we need to find the fraction of the total amount that each part represents. In this case, each part represents 1400/10 = R 140.

Finding the Amount to be Decreased

Since we need to decrease the amount in the ratio 7:3, we need to find the amount that should be decreased from the total amount of R 1400. We can do this by multiplying the fraction of the part that represents the amount to be decreased (which is 3/10) by the total amount of R 1400.

Calculating the Amount to be Decreased

The amount to be decreased is calculated as follows:

Amount to be decreased = (3/10) x R 1400 Amount to be decreased = R 420

Conclusion

Therefore, in order to decrease R 1400 in the ratio 7:3, we need to decrease R 420.

Example

Let's consider an example to illustrate this concept. Suppose we have R 1400 and we need to decrease it in the ratio 7:3. We can calculate the amount to be decreased as follows:

Amount to be decreased = (3/10) x R 1400 Amount to be decreased = R 420

Real-World Applications

This concept has many real-world applications, such as:

Financial Planning: When planning a budget, it's essential to consider the ratio of income to expenses. By decreasing the amount in the ratio 7:3, we can ensure that our expenses are in line with our income.
