Explanation:

To create the biggest number using 12, 1, 4, and 7 with the given operations, we can use the following expression:

12 * (7 - 1) / 4

Let's evaluate it step by step:

1. Perform the subtraction inside the parentheses: 7 - 1 = 6

2. Perform the multiplication: 12 * 6 = 72

3. Perform the division: 72 / 4 = 18

Therefore, the expression 12 * (7 - 1) / 4 yields the biggest number, which is 18.
