Question

(140-12,32):42+3,15*16 7,67:0,65-(0,394+0,7688):0,57 З нижними столбиками

Answer 1

Столбиком не получится написать,это же не ручкой пишешь!
1. (140-12,32 ):42+3,15 ×16=53,44
140-12,32=127,68
127,68 :42=3,04
3,15 ×16=50,4
3,04+50,4=53,44

2. 7,67:0,65-(0,394+0,7688):0,57=9,76
0,394+0,7688=1,1628
7,67:0,65=11,8
1,1628 :0,57= 2,04
11,8-2,04=9,76

Answer 2

To calculate the given expression using the method of "нижні столбики" (bottom-to-top columnar addition and subtraction), we need to perform the operations step by step.

Step 1: Addition and Subtraction (140 - 12) + 32 = 158 42 + 3 = 45 15 * 16 = 240 7.67 / 0.65 = 11.8 (0.394 + 0.7688) = 1.1628

Step 2: Division 11.8 / 0.57 = 20.701754386

Step 3: Final calculation Now, let's combine all the results and calculate the final expression:

158

• 45
• 240
• 20.701754386

• 1.1628

Using the "нижні столбики" method, the final result is:

423.538154386

Therefore, the answer to the expression (140-12,32):42+3,15*16 7,67:0,65-(0,394+0,7688):0,57 using the method of "нижні столбики" is approximately 423.54.
