This math topic focuses on calculating percentage growth of different numbers, specifically identifying what percent a given number increases to reach a new value. The increments are primarily designed around multiples of 5%. Each problem presents two numbers where the first grows to the second, and the task is to determine the percent increase from the original number to the new number. The problems cover varied instances of growth and challenge the learner to apply concepts of percentage increase accurately. This is part of a broader unit on practicing percentage calculations.
