Question

Explain it to a 10 year old

Answer 1

Sure! Multiplying decimals by 1,000 is really easy once you know how to do it. Let’s break it down step by step.

Step 1: Understand what 1,000 means

1,000 is the same as moving the decimal point three places to the right. When you multiply by 1,000, you make the number bigger!

Step 2: Look at the decimal

Let’s take an example: say you have the number 2.5.

Step 3: Move the decimal point

To multiply 2.5 by 1,000:

• First, you find the decimal point. In 2.5, it’s right after the 2: 2.5.

• Now, move that decimal point three places to the right:

  1. Move it once: 25.
  2. Move it twice: 250.
  3. Move it three times: 2500.

So, 2.5 multiplied by 1,000 equals 2,500!

Step 4: Try another example

Let’s say you want to multiply 0.75 by 1,000:

• Find the decimal point in 0.75: 0.75.

• Move the decimal point three places to the right:

  1. Move it once: 7.5.
  2. Move it twice: 75.
  3. Move it three times: 750.

So, 0.75 multiplied by 1,000 equals 750!

Summary

When you multiply any decimal by 1,000, just move the decimal point three places to the right. If you run out of numbers, you can fill in with zeros!

And that’s how you multiply decimals by 1,000! Give it a try with your own numbers!
