Answer 2

To solve the expression 10,78:7,7+(28-21,7)*4,9, let's break it down step by step:

First, let's simplify the expression inside the parentheses (28-21.7): 28 - 21.7 = 6.3

Now, we can substitute this value back into the original expression: 10.78:7.7 + 6.3 * 4.9

Next, let's perform the multiplication: 6.3 * 4.9 = 30.87

Now, let's perform the division: 10.78 : 7.7 = 1.4

Finally, let's add the two results together: 1.4 + 30.87 = 32.27

Therefore, the value of the expression 10,78:7,7+(28-21,7)*4,9 is 32.27.
