Answer:Here's how to find the base for each percentage problem: Understanding the ConceptPercentage: A percentage represents a part out of a hundred.Base: The base is the whole amount that the percentage is calculated from.Part: The part is the portion of the base represented by the percentage. Formula: To find the base, we use the following formula:Base = (Part / Percentage) * 100 Calculations1. 1.2450 is 20% of what number?Base = (1.2450 / 20) * 100= 6.2252. 8 is 25% of what number?Base = (8 / 25) * 100= 323. 16 is 80% of what number?Base = (16 / 80) * 100= 204. 15 is 5% of what number?Base = (15 / 5) * 100= 3005. 6 is 12% of what number?Base = (6 / 12) * 100= 50
