Answer 2

Problem Statement:

On the classroom board, there are 12 words written. One-third of these words were incorrectly copied by Petya into his notebook. How many words did Petya write with errors?

Solution:

To solve this problem, we need to find one-third of the total number of words written on the board.

Let's calculate the number of words Petya wrote with errors:

1. Total number of words on the board: 12 words.

2. One-third of the total number of words: 12 words / 3 = 4 words.

Therefore, Petya wrote 4 words with errors.

Question:

To solve this problem using two steps, we can ask the following question:

"How many words were incorrectly copied by Petya if one-third of the total words on the board were copied incorrectly?"

1. Step 1: Calculate one-third of the total number of words on the board. 2. Step 2: Determine the number of words Petya wrote with errors.

Solution:

Let's solve the problem using the two-step approach:

Step 1: Calculate one-third of the total number of words on the board:

- Total number of words on the board: 12 words. - One-third of the total number of words: 12 words / 3 = 4 words.

Step 2: Determine the number of words Petya wrote with errors:

- Petya wrote 4 words with errors.

Therefore, Petya wrote 4 words with errors.
