Final answer:
To arrange the numbers in ascending order, start by comparing the whole numbers and then move on to the numbers with decimal places.
Step-by-step explanation:
To arrange these numbers in ascending order (smallest first), we start by comparing the whole numbers. In this case, 2.1 is the smallest. Next, we compare the numbers with one decimal place. Here, 4.23 is smaller than 4.43. Finally, we compare the numbers with two decimal places. Since 5.06 is smaller than 7.6, the final ascending order is: 2.1, 4.23, 4.43, 5.06, 7.6, 8.
