Final answer:

The expression simplified in sequence results in the mixed number 8 1/4, considering mixed numbers and fractions.

Step-by-step explanation:

The student's question was, "What is the value of the expression? 934−215+12." To address this question, first, we'll parse the expression correctly. From context, it seems likely that the expression should be −215. Assuming this is the case, the answer would be obtained by performing the subtraction and addition in sequence.

To find the value of the expression correctly, we should convert mixed number 934 to an improper fraction. Since 34 is already in simplest form, we write 934 as 9×4 + 3 over 4, which is 39/4. The expression becomes 39/4 - 215 + 12. We'll convert 2 to a fraction with the same denominator which is 8/4. Now, subtract 8/4 from 39/4 to get 31/4. Adding 1/2 after converting it to 2/4 gives us 33/4, which is a mixed number 81/4.

Finally, we simplify 81/4 to its simplest form, which is 8 with a remainder of 1. This gives us a mixed number answer of 8 1/4.
