Answer:

In order to find the missing addends in the question, we have to do this rule:

In accordance to the question, we have to add first all the available addends, and after that, we can subtract the sum to the sum of the addends to find the missing addend.

1.) 21.002 + 0.918 + ? = 24.98

Solution:

21.002 + 0.918 = 21.92

24.98 - 21.92 = 3.06

Therefore, the missing addend in this question is 3.06.

2.) 1.0098 + ? + 2.98 = 8.6452​

Solution:

1.0098 + 2.98 = 3.9898

8.6452​ - 3.9898 = 4.6554

Therefore, the missing addend in this question is 4.6554.
