- I'm am still confused can someone explain this please

:((5 votes)- It says that Hermoine can lift the feather 5 times higher than Ron, so you just have to divide 35 by 5 that will give you the answer its 7 because 5 goes into 35 7 times(4 votes)

- can someone explain why they did it in a harder and longer way then just doing it quick and easy you could have just done 7x5 and you would get 35 and you know it would be 7(8 votes)
- because its for basic people(1 vote)

- How we divide is simple. If we took the problem 20 divided by 5, this is where we divide. You take five and count up like so- 5, 10, 15, 20. That took us four times, so the answer is four.(6 votes)

## Video 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.
