# Multiplying decimals by 10, 100, and 1000

CCSS.Math:

Practice multiplying decimals by 10, 100, and 1000.

## Part 1: Multiplying decimals by 10

**Key idea:**Multiplying by 10 moves every digit

*one place to the left*.

## Let's try a few more.

## Part 2: Multiplying decimals by 100

**Key idea:**Multiplying by 100 moves every digit

*two places to the left*.

## Let's try a few more.

## Part 3: Multiplying decimals by 1,000

**Key idea:**Multiplying by 1,000 moves every digit

*three places to the left*.

## Let's try a few more.

## Part 4: Let's look at the pattern.

## Part 5: Challenge time!

Use the pattern above to answer the following questions.

- this was hard bragger(0 votes)

- why is it so hard for me(18 votes)
- Another way to think of it is, shift the decimal point to the right. 23 = 23.0 so 23x10 = 230(3 votes)

- the 100's were kinda hard but the 10's were good(21 votes)
- think about like this: if you want to multiply shift the decimal point to the right based on the numbers of zeros. for example if you want to multiply 4.25 X 10 you will shift the decimal point one time to the right (because there is one zero in the ten). if you want to multiply 4.35 X 100 you will shift the decimal point two times to the right because there is two zeros in the 100.(17 votes)
