Evaluate (11)/(12) - (1)/(3) / (1)/(2) without using a calculator.

Here are the solutions to the problems:

1. Without using mathematical tables or a calculator, evaluate:

$$\frac{11}{12} - \frac{1}{3} \div \frac{1}{2}$$

Step 1: Perform the division first according to the order of operations.

$$\frac{1}{3} \div \frac{1}{2} = \frac{1}{3} \times \frac{2}{1} = \frac{2}{3}$$

Step 2: Substitute the result back into the expression.

$$\frac{11}{12} - \frac{2}{3}$$

Step 3: Find a common denominator, which is 12.
