We can evaluate the given expression 4ab/8c by putting the giving values of the variables ( that is, the letters a,b and c) into the given expression. The given expression indicates that we are to find the product of the numerator (4ab) and as well find the products of the denominator (8c). We will then get our answer by dividing the result of the product of the numerator by that of the denominator. From the question, the given values of the variables are as follows:
a = 8; b = 4 and c = 1/2.
Then, for the numerator,
4ab = 4 × 8 × 4 = 128
For the denominator,
8c = 8 × (1/2) = 4.
Our final answer will then become
128 ÷ 4 = 32.
Hence, for the given values, the expression is evaluated as 32.
