## Guide to Multiplying 2-Digit by 1-Digit with Partial Products

**Breaking Down the Numbers**

To multiply a 2-digit number by a 1-digit number, start by understanding the place values. For example, in the number 37:

3 is in the tens place, representing 30.

7 is in the ones place, representing 7.

**Applying the Distributive Property**

The distributive property helps simplify multiplication by breaking down the numbers:

Split the 2-digit number into tens and ones. For 37, this means 30 and 7.

Multiply each part by the 1-digit number separately.

Using 37 x 6 as an example:

Multiply the tens: 30×6=18030 \times 6 = 18030×6=180

Multiply the ones: 7×6=427 \times 6 = 427×6=42

**Adding the Partial Products**

Next, add the results of these multiplications together:

180+42=222180 + 42 = 222180+42=222

**Step-by-Step Approach**

Write the 2-digit number and the 1-digit number.

Break down the 2-digit number into its tens and ones.

Multiply each part by the 1-digit number.

Add the partial products to get the final result.

By following this method, you can easily multiply any 2-digit number by a 1-digit number, ensuring accuracy and understanding of the multiplication process.
