Solution method for Exercise 2 on Page 42 Math 5 Textbook
Problem: Write the following numbers in descending order: 0.32, 0.197, 0.4, 0.321, 0.187
Solution method:
* Observation: The given decimal numbers all have the same integer part, so we compare the decimal part of each number.
* Solution: Compare the digits in each decimal place of each number, the digit corresponding to the largest decimal place is placed first, followed by the smaller numbers,... and the smallest is placed last (because the problem requires arranging in descending order).
