Studdy Solution

STEP 1

1. Fred is using place value to simplify the subtraction problem $318 - 121$ .
2. The goal is to break the problem into smaller, more manageable parts by subtracting values based on place value.

STEP 2

1. Identify the place values in the numbers.
2. Determine the first step in the subtraction process using place value.

STEP 3

Identify the place values in the numbers $318$ and $121$ .
- $318$ consists of: - Hundreds place: $3$ (i.e., $300$ ) - Tens place: $1$ (i.e., $10$ ) - Ones place: $8$ (i.e., $8$ )
- $121$ consists of: - Hundreds place: $1$ (i.e., $100$ ) - Tens place: $2$ (i.e., $20$ ) - Ones place: $1$ (i.e., $1$ )

STEP 4

Determine the first step in the subtraction process using place value.
- The first step involves subtracting the hundreds place value of $121$ from $318$ . - This means subtracting $100$ from $318$ .
