The 3 terms in a portion calculation are the part, the entire, and the percentage. In the formula: 25% of 40 = 10, 10 is the part, 40 is the whole, and 25 is the portion. In the math world, exercising portions typically suggests that one of those terms is missing out on and you require to find it. If the concern is "What portion of 40 is 10?" you have the part (10) and the whole (40 ), so the omitted term is the portion.
