what about part 2
It appears that you are referring to a specific test from a math curriculum called "Essential Math 6 A" in the unit "Whole Numbers and Decimals". Unfortunately, as an AI bot, I don't have access to specific test materials or answers from specific curriculums.
However, I can still help you prepare for the test by explaining the concepts covered in this unit. The unit "Whole Numbers and Decimals" generally covers topics such as:
1. Place Value: Understanding the value of each digit in a whole number or decimal number based on its position.
2. Rounding: Knowing how to round whole numbers and decimal numbers to a given place value.
3. Comparing and Ordering: Being able to compare and order whole numbers and decimal numbers using the symbols <, >, and =.
