Answer 1

1)31.7:63.4=0.5
2)23.4:(-1.17)=-20
3)0.5-(-20)=20.5
4)20.5*(-2.4)= -49.2

Answer 2

Let's solve the expression step by step:

1. First, calculate the value inside the innermost parentheses: (31.7 : 63.4 - 23.4 : (-1.17))

   We perform the divisions first: (0.5 - (-20.0))

   Next, perform the subtraction: (0.5 + 20.0) = 20.5

2. Now, evaluate the expression with the remaining parentheses: (20.5) * (-2.4)

   Multiplication: -49.2

The result of the expression is -49.2.
