Answer 1

Ответ:

-1,1-(1,7-10,8)+8(-2 3/8+1 3/16)=

-1,1-(-9,1)+8(-19/8+19/16)=

-1,1+9,1+8(19/16)=

-1,1+9,1-19/2=

-1,1+9,1-9,5=

1,5 ну как-то так

Answer 2

Let's break down the expression step by step:

1. Start with the subtraction inside the parentheses: (1,7 - 10,8) 1.7 - 10.8 = -9.1

2. Add the result of the subtraction to the initial -1,1: -1.1 + (-9.1) = -10.2

3. Next, let's deal with the expression inside the second set of parentheses: (-2 3/8 + 1 3/16)

   • Convert the mixed numbers to improper fractions: -2 3/8 = -19/8 1 3/16 = 19/16

   • Add the fractions: -19/8 + 19/16 = (-38 + 19) / 16 = -19/16

4. Finally, multiply the result from step 3 by 8: -19/16 * 8 = -19/2 = -9.5

5. Add the result from step 2 to the result from step 4: -10.2 + (-9.5) = -19.7

So, the final result of the expression is approximately -19.7.
