Answer 1

Ответ:

Пошаговое объяснение:

3/5:2=3/5*1/2=3/10

3/10:9=3/10*1/9=1/30

1/30:1 4/5=1/30*5/9=1/54

1.2*4=4.8

4.8-1/54=4 4/5-1/54=4 216/270-5/270=4 211/270

Answer 2

Let's solve the expression step by step:

1. 3/5:2 = (3/5) / 2 = 3/10

2. 9:1 = 9 (since any number divided by 1 is the number itself).

3. 4/5 - 1 = (4/5) - (5/5) = (4/5) - 1 = -1/5

4. Now, let's calculate 2 * 4 = 8.

5. Finally, -1/5 * 8 = -8/5.

So, the expression 3/5:2:9:1 4/5 - 1,2 * 4 is equal to -8/5.
