Question

201-(140,7:13,4+1,6)*2,8

Answer 1

1) 140.7:13.4=10.5
2) 10.5+1.6=12.1
3) 12.1×2.8=33.88
4) 201-33.88=167.12

Answer 2

To solve the expression 201-(140,7:13,4+1,6)*2,8, let's break it down step by step:

First, we need to simplify the expression within the parentheses: 140,7:13,4+1,6.

In this expression, the comma (",") represents a decimal point. Therefore, we have two numbers: 140.7 and 13.4+1.6.

Now, let's simplify the second part: 13.4+1.6 = 15.

Now we can rewrite the expression as: 140.7,15.

The colon (":") represents concatenation. So, we concatenate the two numbers: 140.715.

Now let's go back to the original expression: 201-(140,7:13,4+1,6)*2,8.

Next, we need to multiply the concatenated number (140.715) by 2.8: 140.715 * 2.8 = 394.602.

Finally, we subtract 394.602 from 201: 201 - 394.602 ≈ -193.602.

Therefore, the result of the expression 201-(140,7:13,4+1,6)*2,8 is approximately -193.602.
