Ответ:

Пошаговое объяснение:

4,25*2 1/5=4, 25*2,2=9,35

10,3-9,35=0,95

0,95:2/19=19/25*19/2=361/50=7,22

Answer 2

Let's solve the expression step by step:

Step 1: Simplify the expression inside the parentheses 10,3 - 4,25 × 2 = 10.3 - 8.5 = 1.8

Step 2: Convert the fraction to a decimal 1 пятая (1/5) = 1 ÷ 5 = 0.2

Step 3: Multiply the result from Step 1 by the decimal from Step 2 1.8 × 0.2 = 0.36

Step 4: Convert the divisor to a decimal 2 19деадцатых (2 19/12) = 2 + 19/12 = 2 + 1.5833... ≈ 3.5833 (rounded to 4 decimal places)

Step 5: Divide the result from Step 3 by the decimal from Step 4 0.36 ÷ 3.5833 ≈ 0.1004336 (rounded to 7 decimal places)

So, the final result is approximately 0.1004336.
