Answer 2

Let's solve each of these mathematical expressions step by step:

1. 8.39 + 17.51 and 30 - 4.1:
   • First, add 8.39 and 17.51: 8.39 + 17.51 = 26.90
   • Then, subtract 4.1 from 30: 30 - 4.1 = 25.9

So, the result of the first expression is 26.90 and 25.9.

2. 81.27 - 35.2 and 24.9 + 21.18:
   • First, subtract 35.2 from 81.27: 81.27 - 35.2 = 46.07
   • Then, add 24.9 and 21.18: 24.9 + 21.18 = 46.08

So, the result of the second expression is 46.07 and 46.08.

3. 100 - 81.25 and 13.34 + 6.4:
   • First, subtract 81.25 from 100: 100 - 81.25 = 18.75
   • Then, add 13.34 and 6.4: 13.34 + 6.4 = 19.74

So, the result of the third expression is 18.75 and 19.74.

4. 202.09 - 183.82 and 300.233 - 281.963:
   • First, subtract 183.82 from 202.09: 202.09 - 183.82 = 18.27
   • Then, subtract 281.963 from 300.233: 300.233 - 281.963 = 18.27

So, the result of the fourth expression is 18.27 and 18.27.

These are the results of each expression.
