Пошаговое объяснение:

13,7-19/5 : -38/10 - 645/10 : 6 + 16/7*21/10=13,7 + 1 - 10,75 + 4,8 = 19,5 -10,75=8,75

Answer 2

Let's solve the expression step by step:

1. Subtract 3 4/5 from 13 7/10: 13 7/10 - 3 4/5 = 13.7 - 3.8 = 9.9

2. Divide 9.9 by (3,8): 9.9 / (3.8) ≈ 2.60526316 (rounded to 8 decimal places)

3. Subtract 64,5 from the result: 2.60526316 - 64.5 ≈ -61.89473684 (rounded to 8 decimal places)

4. Divide -61.89473684 by 6: -61.89473684 / 6 ≈ -10.31578947 (rounded to 8 decimal places)

5. Add 4 2/7 to the result: -10.31578947 + 4 2/7 = -10.31578947 + 4.28571429 ≈ -6.03007518 (rounded to 8 decimal places)

6. Multiply by 2,1: -6.03007518 * 2.1 ≈ -12.66215588 (rounded to 8 decimal places)

So, the final result is approximately -12.66215588.
