To determine which statement is true about Jerome's work, let's first calculate the product of 589 × 12.
-
First, we can break it down:
- 589 × 10 = 5890
- 589 × 2 = 1178
-
Now, add the two results together:
- 5890 + 1178 = 7068
So, 589 × 12 = 7068.
Now, let's analyze the statements:
-
"Jerome added incorrectly." - We would need specific details on his addition. Since we calculated it correctly, we can't conclude this without knowing his work.
-
"Jerome forgot to carry the 1 when he multiplied 2 × 9." - In the multiplication step of 2 × 9, if he had the carry-over from previous multiplications (if it were part of the multi-digit multiplication), this statement could be true. If he did not carry properly, it would affect the final result.
-
"Jerome forgot to use 0 as a placeholder." - This statement usually applies when multiplying multi-digit numbers, but in this case, each digit has been accounted for correctly in the multiplication process, so it's unlikely he's neglected placeholders.
-
"Jerome solved the problem correctly." - This statement is true based on our calculation, provided he followed the proper steps correctly in his work.
Without specific evidence of how Jerome worked through the multiplication and to avoid assumptions, the safest choice based on our calculation is that he solved the product correctly.
Answer: Jerome solved the problem correctly.
