About this video
Hermione lifts a feather 35 feet, which is 5 times as high as Ron. To find Ron's height we divide: 35 / 5 = 7 feet. The video checks this by seeing that 5 x ? = 35 is the same as 35 / 5 = ?.
You'll be able to
- solve a 'times as high' comparison when I know the bigger amount.
- explain why 5 x ? = 35 and 35 / 5 = ? ask the same question.
Key words
- divide
- Split a total into equal groups to find how much is in each group.
- comparison
- A sentence that tells how two amounts are related, like '5 times as high as'.
Transcript
Ron and Hermione are practicing lifting feathers into the air with magic. Hermione can lift a feather 35 feet into the air, which is 5 times as high as Ron can lift a feather. How high can Ron lift a feather with his magic? So Hermione, this 35 feet is 5 times more than Ron.
So to figure out what Ron can do, we just take what Hermione can do and divide by 5. So what's 35 divided by 5? Well, 5 times 7 is 35. So 35 divided by 5 is 7. So Ron can lift a feather 7 feet in the air. So let's check our answer. Now, if you have trouble with this-- and we could also look at the hints for this.
So they show that Hermione can lift a feather 35 feet, which is 5 times higher than Ron. So this could be the length of how high Ron can raise it. And so, if you were to actually divide 35 into 5 equal sections, so 5 times question mark is 35, that's the same thing as saying 35 divided by 5 is question mark.
And 35 divided by 5 is indeed 7.
