Question

(D E) ÷ (D/E) where D = -1 1/2 and E = -1. The result of this expression is:

A) 2
B) -1/2
C) -1
D) 1/2

Answer 1

To evaluate the expression (D E) ÷ (D/E) where D = -1 1/2 and E = -1, substitute the given values into the expression and simplify.

Step-by-step explanation:

To evaluate the expression (D E) ÷ (D/E) where D = -1 1/2 and E = -1, we substitute the given values of D and E into the expression.

First, we calculate D E: (-1 1/2)(-1) = 1 1/2 = 3/2.

Next, we calculate D/E: (-1 1/2)/(-1) = 3/2/(-1) = (3/2) * (-1) = -3/2.

Finally, we divide D E by D/E: (D E) ÷ (D/E) = (3/2) ÷ (-3/2) = (3/2)*(-2/3) = -1/2.

Therefore, the result of the expression is B) -1/2.
