Question

(3,12+0,9)⋅(1−0,4)= 15,76267÷(100,6+42,697)= (13−29,76÷32)⋅0,89−0,0423=

Answer 1

Ответ:

1)4,02*0,6=2,412

2)15,76267:142297=0,11

3)(13-29,76:32)*0,89-0,0423=10,7423=10,7

Answer 2

Let's break down the calculations step by step:

1. (3,12 + 0,9) = 4.02
2. (1 - 0,4) = 0.6
3. 4.02 * 0.6 = 2.412

Next,

1. (13 - 29.76 ÷ 32) = 12.07
2. 12.07 * 0.89 = 10.7253
3. 10.7253 - 0.0423 = 10.6827

Finally,

1. 15.76267 ÷ (100.6 + 42.697) = 0.1089

So, the final result is:

2.412 ÷ 0.1089 ≈ 22.1475 (rounded to four decimal places)
