What must you add to the ratio of gap to target to obtain the target achievement percentage?

To derive the target achievement percentage from the ratio of gap to target, it is essential to add 100 to the gap-to-target ratio. The target achievement percentage is calculated as follows:

1. The target itself represents the goal set for a given metric.

2. The gap is the difference between the current performance and the target.

The formula to calculate the target achievement percentage would be:

Target Achievement Percentage = (Current Performance / Target) * 100.

When you syntactically represent the ratio of gap to target, this can also be seen mathematically as:

Target Achievement Percentage = (Target - Gap) / Target * 100.

To transition from the gap-to-target ratio to the percentage, you need to add 100 to account for the portion that represents actual progress toward the target. This ensures that when you convert the fraction into a percentage, you properly adjust for the total amount (100%).

Therefore, adding 100 to the ratio of gap to target is necessary to obtain the target achievement percentage.
