Question

39,5*2-3,5*2/57,5*2-14,5*2

Answer 1

Ответ: 1/

(39.5 + 3.5) (39.5 - 3.5) / (57.5 + 14.5)(57.5-14.5) ] =36 * 43 / 72 * 43 = 1/2

Answer 2

Let's break down the expression step by step:

1. 39.5 * 2 = 79
2. 3.5 * 2 = 7
3. 57.5 * 2 = 115
4. 14.5 * 2 = 29

Now, let's perform the calculations:

(79 - 7) / (115 - 29)

Now, subtract within the parentheses:

72 / 86

Now, divide:

72 / 86 ≈ 0.8372

So, the result of the expression is approximately 0.8372.
