$(5,05:\frac1{40}-2,8\cdot\frac56)\cdot3+(-16)\cdot(0,1875)\\1)\;5,05:\frac1{40}=5,05\cdot40=202\\2)\;2,8\cdot\frac56=\frac{14}6=\frac73=2\frac13\\3)\;202-2\frac13=199\frac23=\frac{599}3\\4)\;\frac{599}3\cdot3=599\\5)\;(-16)\cdot(0,1875)=-1,125\\6)\;599+(-1,125)=599-1,125=597,875$

Answer 2

To solve the expression (5,05:1/40-2,8*5/6)3+(-16)(0,1875), let's break it down step by step:

1. First, let's simplify the multiplication and division operations within parentheses:

(5,05:1/40 - 2,8 * 5/6) * 3 + (-16) * 0,1875

Convert the decimal comma to a decimal point:

(5.05:1/40 - 2.8 * 5/6) * 3 + (-16) * 0.1875

2. Next, let's perform the division operation 5.05:1/40:

5.05:1/40 = 5.05 / (1/40) = 5.05 * 40 = 202

Now, the expression becomes:

(202 - 2.8 * 5/6) * 3 + (-16) * 0.1875

3. Perform the multiplication 2.8 * 5/6:

2.8 * 5/6 = 14/6 = 7/3

Now, the expression becomes:

(202 - 7/3) * 3 + (-16) * 0.1875

4. Simplify the expression within the parentheses:

202 - 7/3 = (202 * 3 - 7) / 3 = (606 - 7) / 3 = 599/3

Now, the expression becomes:

(599/3) * 3 + (-16) * 0.1875

5. Perform the multiplication (599/3) * 3:

(599/3) * 3 = 599

Now, the expression becomes:

599 + (-16) * 0.1875

6. Perform the multiplication (-16) * 0.1875:

(-16) * 0.1875 = -3

Now, the expression becomes:

599 + (-3)

7. Finally, perform the addition:

599 + (-3) = 596

Therefore, the value of the expression (5,05:1/40-2,8*5/6)3+(-16)(0,1875) is 596.
