Question

(4\7*2,8-16\5)*(7\3*0,018-3\8)

Answer 1

4/7*28/10=16/10=1,6
1,6-3,2=-1,6
7/3*18/1000=42/1000=0,042
0,042-0,375=-0,333
-1,6*(-0,333)=0,5328

Answer 2

  4  * 2,8      16        7 * 0,018     3
(  ----------   - ----) * ( ---------------- - ---)= (1,6 - 3,2) *(0,042 - 0,375)
      7           5            3             8

Дальше сам, результат положительный, т. к. оба сомножителя отрицательные

Answer 3

Let's break down the expression step by step:

1. First, perform the calculations inside the parentheses on both sides of the multiplication operator (*):

   On the left side: (4/7 * 2.8 - 16/5)

   On the right side: (7/3 * 0.018 - 3/8)

2. Calculate each of these expressions:

   Left side: (4/7 * 2.8 - 16/5) = (1.6 - 3.2) = -1.6

   Right side: (7/3 * 0.018 - 3/8) = (0.042 - 0.375) = -0.333

3. Now, multiply the results of the two sides together:

   (-1.6) * (-0.333) = 0.5336

So, the final result of the expression is approximately 0.5336.
