Lesson 50: Multiplying and dividing decimals by 10, 100, and 1000

# Dividing decimals by 10, 100, and 1000

Practice dividing decimals by 10, 100, and 1000.

## Part 1: Dividing decimals by 10

Key idea: Dividing by $10$ moves every digit one place to the right.
Let's visualize it! Drag the dot all the way to the right.
$5.14÷10=$

## Let's try a few more dividing by $10$‍ :

$44.2÷10=$

$145.18÷10=$

$0.678÷10=$

And one multiplying by $10$ (for review):
$0.933×10=$

## Part 2: Dividing decimals by 100

Key idea: Dividing by $100$ moves every digit two places to the right.
Let's visualize it! Drag the dot all the way to the right.
Notice that we add zeros to fill the empty place values.
$2.8÷100=$

## Let's try a few more dividing by $100$‍ :

$6.33÷100=$

$71.005÷100=$

$189.2÷100=$

And one multiplying by $100$ (for review):
$5.4×100=$

## Part 3: Dividing decimals by 1000

Key idea: Dividing by $1000$ moves every digit three places to the right.
Let's visualize it! Drag the dot all the way to the right.
Notice that we add zeros to fill the empty place values.
$0.6÷1000=$

## Let's try a few more dividing by $1000$‍ :

$7500.9÷1000=$

$0.1÷1000=$

$623.88÷1000=$

And one multiplying by $1000$ (for review):
$0.0043×1000=$

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

Dividing by $10$ moves every digit $1$ place to the right.
Dividing by $100$ moves every digit $2$ places to the right.
Dividing by $1000$ moves every digit $3$ places to the right.
Dividing by $100,000$ moves every digit
places to the right.
Dividing by $1,000,000$ moves every digit
places to the right.

## Part 5: Challenge time!

Use the pattern above to answer the following questions.
$333.4÷100,000=$

$29.7÷1,000,000=$

And a multiplication challenge:
$0.055×10,000=$
