Answer 2

Let's solve these expressions step by step:

1. 2,46:4,1 + 15:0,25 - 4:25 - 14,4:0,32

First, let's simplify the divisions and multiplications:

2.46 ÷ 4.1 + 60 - 0.16 - 14.4 ÷ 0.32

Now, perform the additions and subtractions from left to right:

0.6 + 60 - 0.16 - 45

Now, continue with the additions and subtractions:

0.6 + 60 - 0.16 - 45 = 0.44 - 45

Finally, subtract 45 from 0.44:

0.44 - 45 ≈ -44.56

So, the result of the first expression is approximately -44.56.

2. 50 - (2.3256 ÷ 0.068 + 9.38)

First, let's simplify the division and addition inside the parentheses:

2.3256 ÷ 0.068 + 9.38

Now, calculate the result:

34.15176 + 9.38

Now, add the two values together:

34.15176 + 9.38 ≈ 43.53176

Finally, subtract this result from 50:

50 - 43.53176 ≈ 6.46824

So, the result of the second expression is approximately 6.47.
