Answer 2

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

4. 0.63 * 12 + 0.9 * 30 - 25.56

First, multiply 0.63 by 12: 0.63 * 12 = 7.56

Next, multiply 0.9 by 30: 0.9 * 30 = 27

Now, subtract 25.56: 7.56 + 27 - 25.56 = 9

So, the result of the expression is 9.

5. 83 - (17.27 * 10 - 8.93 * 11)

First, multiply 17.27 by 10: 17.27 * 10 = 172.7

Next, multiply 8.93 by 11: 8.93 * 11 = 98.23

Now, subtract the result of the second multiplication from the first multiplication and then subtract the result from 83: 83 - (172.7 - 98.23) = 83 - 74.47 = 8.53

So, the result of the expression is 8.53.

6. 791.8 - (28.31 * 40 - 580.9)

First, multiply 28.31 by 40: 28.31 * 40 = 1132.4

Next, subtract 580.9 from the result: 1132.4 - 580.9 = 551.5

Now, subtract the result from 791.8: 791.8 - 551.5 = 240.3

So, the result of the expression is 240.3.
