Final answer:
Simplify the expression and write the answer as a fraction in simplest form: -4/5.
To evaluate 1/2abcd, substitute the values of a, b, c, and d.
Step-by-step explanation:
To evaluate 1/2abcd, we substitute the values of a, b, c, and d.
a = -2.4
b = -5/6
c = -1 1/5
d = 2/3
Substituting these values, we get:
1/2*(-2.4)*(-5/6)*(-1 1/5)*2/3
Next, we simplify the expression:
1/2*(-2.4)*(-5/6)*(-6/5)*2/3
Now, we multiply and divide:
1/2*(-2.4)*(-1)*2/3
-1*(2.4)*(2)/6
-2.4*2/6
-4.8/6
Simplifying the fraction, we get -4/5.
