Using the formula P × V1 = V2 to calculate the percentage, where P is the percentage, V1 is the first value that the percentage will modify, and V2 is the result of the percentage operating on V1. We have:
P = Percentage, V1 = 25, V2 = 40
We want to find the percentage (P), given that 25 is a part of 40. Setting up the equation: 25 × 40 = P × 40).
Solving for P, we have:
P = (25 × 40) / 40
P = 1000 / 40
P = 25
Therefore, 25 is 25 of 40, making up 25% of 40.
