Answer 2

Let's solve the mathematical expressions step by step:

1. 80.3 - 4.2 : 25 * 40

First, let's perform the division: 4.2 : 25 = 0.168

Now, the expression becomes: 80.3 - 0.168 * 40

Next, perform the multiplication: 0.168 * 40 = 6.72

Now, the expression becomes: 80.3 - 6.72

Finally, perform the subtraction: 80.3 - 6.72 = 73.58

So, the result of the first expression is 73.58.

2. (3.27 : 5 + 73.4 : 50) * 0.2 + 37.39

Let's start by performing the divisions: 3.27 : 5 = 0.654 and 73.4 : 50 = 1.468

Now, the expression becomes: (0.654 + 1.468) * 0.2 + 37.39

Next, perform the addition: 0.654 + 1.468 = 2.122

Now, the expression becomes: 2.122 * 0.2 + 37.39

Next, perform the multiplication: 2.122 * 0.2 = 0.4244

Now, the expression becomes: 0.4244 + 37.39

Finally, perform the addition: 0.4244 + 37.39 = 37.8144

So, the result of the second expression is 37.8144.

In summary:

1. 80.3 - 4.2 : 25 * 40 = 73.58
2. (3.27 : 5 + 73.4 : 50) * 0.2 + 37.39 = 37.8144
