Answer 2

To evaluate the expression (3/4 + 1/20) * 1/2, we can follow the order of operations, which states that multiplication and division should be done before addition and subtraction.

Let's calculate it step by step:

1. Simplify the addition inside the parentheses: 3/4 + 1/20. To add fractions, we need to find a common denominator. The least common multiple (LCM) of 4 and 20 is 20.

   3/4 + 1/20 = (3 * 5)/(4 * 5) + 1/20 = 15/20 + 1/20 = (15 + 1)/20 = 16/20

2. Multiply the result from step 1 by 1/2: (16/20) * (1/2) = (16 * 1)/(20 * 2) = 16/40 = 4/10

The final result is 4/10, which can be simplified further as 2/5.

Therefore, (3/4 + 1/20) * 1/2 equals 2/5.
