This math topic focuses on calculating the whole number from a given part and its corresponding percentage, specifically in 10% increments. The tasks involve understanding and applying the concept of percentages to find what total number a specific portion represents when given as 10%, 20%, and 30% of it. The questions provide a portion of the number and state its percentage; learners are required to deduce the full value based on those percentages. Each problem presents multiple-choice answers to select the correct total number.
