Question

161-(469,7:15,4+9,52)-1,5

Answer 1

161-(469,7:15,4+9,52)-1,5 1) 469,7:15,4=30,5 2)30,5+9,52=40,02 3)161-40,02=120,98 4)120,98-1,5=119,48 Ответ: 119,48

Answer 2

Let's break down the given expression:

• 469,7:15 refers to the substring of the number 469 starting from index 7 (inclusive) and ending at index 15 (exclusive). That means we are taking the digits "7" and "8" from 469, so we can replace that part with "78".
• 4+9 equals 13, so we can replace that part with "13".
• 52 is already a number, so we can leave that part as is.

Now our expression becomes:

161-(78+13-52)-1,5

Next, we need to perform the arithmetic inside the parentheses first, using the order of operations:

78+13-52 = 39

So the expression becomes:

161-39-1,5

We can simplify further by subtracting 39 from 161, and then subtracting 1.5 from the result:

121.5

Therefore, the final answer is 121.5.
