-3/4 + 8.5(0.021 ÷ 0.01 - 2.51)
First, we need to simplify the expression inside the parentheses0.021 ÷ 0.01 = 2.0.021 ÷ 0.01 - 2.51 = 2.1 - 2.51 = -0.41
Now we substitute this back into the original equation-3/4 + 8.5(-0.41)
Next, we multiply 8.5 by -0.41-3/4 + (-3.485)
Now we add the two terms together to get-3.485 - 0.75 ≈ - 4.24
Therefore, -3/4 + 8.5(0.021 ÷ 0.01 - 2.51) ≈ -4.24
-3/4 + 8.5(0.021 ÷ 0.01 - 2.51)
First, we need to simplify the expression inside the parentheses
0.021 ÷ 0.01 = 2.
0.021 ÷ 0.01 - 2.51 = 2.1 - 2.51 = -0.41
Now we substitute this back into the original equation
-3/4 + 8.5(-0.41)
Next, we multiply 8.5 by -0.41
-3/4 + (-3.485)
Now we add the two terms together to get
-3.485 - 0.75 ≈ - 4.24
Therefore, -3/4 + 8.5(0.021 ÷ 0.01 - 2.51) ≈ -4.24
