Question

3,2*(-5)-(-4,8):(-ТРИ 1/5)

Answer 1

1) 3,2*(-5)= -16
2)-4,8:(-три1/5)= -одна целая 1/2
3)-16-(-одна целая 1/2)=14целых 1/2
Ответ: 14целых 1/2

Answer 2

To simplify the expression, let's perform the operations step by step:

Step 1: Evaluate 3,2*(-5) Since there's a comma in the number 3,2, it seems like you are using a different notation for decimals. I'll assume the comma represents a decimal point. So, 3,2 is equal to 3.2. Now, multiply 3.2 by -5: 3.2 * (-5) = -16.

Step 2: Evaluate -(-4,8) Similarly, assuming the comma represents a decimal point, -4,8 is equal to -4.8. To remove the double negative, we change it to a positive value: -(-4.8) = 4.8.

Step 3: Evaluate (-ТРИ 1/5) It appears that you have written "ТРИ," which means "three" in Russian, but it's not clear if you want to use it as a variable or as the number 3. Since the context is unclear, I'll assume you meant "three" and evaluate the expression accordingly.

Three and one-fifth as a fraction is 3 + 1/5 = 3.2 (assuming the comma represents a decimal point).

Now, let's put all the steps together and evaluate the expression:

3,2*(-5) - (-4,8) / (-ТРИ 1/5)

Substituting the values: -16 - 4.8 / 3.2

Now, perform the division first: -16 - 1.5

Finally, subtract the values: -17.5

So, the simplified result of the expression is -17.5.
