Hello!
99 to 74 would be a percentage decrease. To find the percentage decrease, we must use the formula:
Percent Decrease Formula: {(Old Value - New Value) / Old Value × 100}
Substitute: {(99 - 74) / 99 × 100}
Solve:
99 - 74 = 25
25 / 99 = 0.25 (Repeating)
0.25 (Repeating) × 100 = 25.25 (Repeating)
You may round this to 25, or simply put a bar over the 25 after the decimal point, and the bar would indicate that it is a repeating decimal.
The percentage decrease is about 25%.
