Multiplying decimals by 10, 100, and 1000
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!

- this is so easy(52 votes)
- it might be hard for other people(16 votes)
- why is it so hard for me(32 votes)
- Another way to think of it is, shift the decimal point to the right. 23 = 23.0 so 23x10 = 230(20 votes)
- the 100's were kinda hard but the 10's were good(32 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.(33 votes)
