Then, I also show where this shortcut originates, using place value charts. In reality, the decimal point moving is sort of an illusion, and instead, the digits of the number move within the place value chart.

When the multiplier is 10, or , we move the decimal point to the right by as many places as number of zeroes after 1 in the multiplier. To multiply a decimal by 10, move the decimal point in the multiplicant by one place to the right. To multiply a decimal by , move the decimal point in the multiplicant by two places to the right. To multiply a decimal by , move the decimal point in the multiplicant by three places to the right.

Current timeTotal duration Math: 5. Google Classroom Facebook Twitter. Video transcript - [Instructor] In this video, we're going to get a little bit of practice multiplying and dividing decimals by 10, , and So let's just start with a little bit of a warmup.

If I were to say, what is 2. Pause this video and see if you can figure that out. Well, in previous videos, we've already said that when you multiply by 10, you shift each of the digits one place to the left.

And so this is going to be equal to, instead of two ones, we're now going to have two 10s, so two in the tens place. And then, instead of zero tenths, we're now going to have zero ones. And instead of five hundredths, we're now going to have five tenths, so this is equal to Now what if we were to go the other way around?

What if we were to say 2. Pause the video and see if you can figure that out. Well here, all of our digits are going to shift one place to the right because we're dividing by And so our two ones are going to become two tenths, so this is going to be zero point, so we're gonna have two tenths now. Our zero tenths are going be zero hundredths, and then our five hundredths are going to be five thousandths, we've covered that in other videos, but now let's do this with, say, or So if I were to ask you what is 57 divided by ?

Pause this video and see if you can work that out. All right, now let's do this together. So when you divide by , that's the same thing as dividing by 10 three times. So that's 10s, ones, tenths, hundredths, thousandths, and so our five was in the 10s place, it's five 10s, so it was here, but we're going to shift three places to the right. One, two, three. So our five will go there. So what was five 10s is now five hundredths. And then our seven is similarly going to, it was in the ones place, but we're gonna shift three places to the right.

And there you have it. What was just 57 is now 57 thousandths. And to make that very clear, I'll put a zero in the tenths place and a zero in the ones place, and that makes sense. So as another example, let's say someone walks up to you on the street and says I started with 1. What did they multiply by to get Pause this video and try to work it out.

Well to understand this, we just have to think well, how much did each digit get shifted by? So what was in the ones place got shifted not just to the 10s place, but it got shifted to the hundreds place. So it got shifted two places to the left. The zero, similarly, got shifted two places to the left. From the tenths to the 10s, and if you look at it, every digit got shifted two places to the left. And we must have multiplied by 10 twice, so you could say times 10 times 10, or you could just rewrite this as times Let's just do one more example for kicks.

Let's say that someone were to say what is 0. All right, well, like we've done before, we're just going to shift every digit two places to the left. So the one, which is in the hundredths place, is going to end up in the ones place, and then the five, which is in the thousandths place, is going to end up in the tenths place.

So this is going to be equal to 1. Multiply and divide decimals by Multiply and divide decimals by 10, , and Up Next.

Сьюзан так и подумала. Старшие должностные лица АНБ имели право разбираться со своими кризисными ситуациями, не уведомляя об этом исполнительную власть страны. АНБ было единственной разведывательной организацией США, освобожденной от обязанности отчитываться перед федеральным правительством. Стратмор нередко пользовался этой привилегией: он предпочитал творить свое волшебство в уединении. - Коммандер, - все же возразила она, - это слишком крупная неприятность, и с ней не стоит оставаться наедине. Вам следовало бы привлечь кого-то. - Сьюзан, появление Цифровой крепости влечет за собой очень серьезные последствия для всего будущего нашего агентства.

 Да-да. Сегодня мой брат Клаус нанял девушку, очень красивую. С рыжими волосами. Я тоже хочу. На завтрашний день, пожалуйста. - Ваш брат Клаус приходил к нам? - Женщина вдруг оживилась, словно говорила со старым знакомым.
