Final answer:
To arrange each group in descending order, compare the numbers and sort them from largest to smallest. Group a: 0.44, 0.4, 0.04. Group b: 2.16, 2.026, 2.016. Group c: 0.98, 0.932, 0.895.
Step-by-step explanation:
To arrange each group in descending order, we need to compare the numbers and sort them from largest to smallest.
For group a, the numbers are 0.4, 0.04, and 0.44. The descending order would be 0.44, 0.4, 0.04.
For group b, the numbers are 2.16, 2.016, and 2.026. The descending order would be 2.16, 2.026, 2.016.
For group c, the numbers are 0.932, 0.98, and 0.895. The descending order would be 0.98, 0.932, 0.895.
