It looks like the student is attempting a long division problem with the numbers 432 being divided by 12. From the details you've provided, it appears that they made an error in several steps. Let's break it down to identify the first error:
-
Step 1: Identifying how many times 12 goes into 43.
- 12 goes into 43 three times (3 × 12 = 36).
- The student seems to have placed the 3 in the wrong location or already made an error in this step, as it should be 3.
-
Step 2: Subtracting.
- If they correctly subtracted 36 from 43, they would write:
- 43 - 36 = 7.
- If they correctly subtracted 36 from 43, they would write:
-
Step 3: Bringing down the next digit (2), making it 72.
- The next step would be calculating how many times 12 goes into 72.
- 12 goes into 72 six times (6 × 12 = 72).
-
Step 4: Subtracting again.
- 72 - 72 = 0.
- They would then write the final quotient above the division, which is 36.
Summary of Errors:
The first error appears when they determine how many times 12 goes into 43. They should have stated that 12 goes into 43 three times, instead of what they had written.
