ANOTHER... word problem!

I have one more word problem, its annoying because it looks so easy...
yet my answer is wrong.

11. If one hanging garment uses 2cm of space, how many rails of 0.5m can you fill with
200 garments?


i did this: 200/2 = 100

lol which is wrong!

Can anyone help?

many thanks

Hello Angelina,

If 1 garment uses in 2 cm of space, haw many space do 200 garments take in? How many rails of 50 cm are equivalent to that space?

Re: ANOTHER... word problem!

1 garment uses 1*2 cm of space,
200 garments use 200*2 cm=400 cm of space.

1 rails takes in 50 cm.
4 rails take 4*50cm=200cm of space.
n rails take n*50=50n cm of space. You donīt want 200 cm, but 400 cm. What value should "n" have?

Re: ANOTHER... word problem!

1 garment takes 2cm of space.
2 garments take 4cm of space.
3 garments take 6cm of space.
4 garments take 8cm of space.
...
(notice the pattern)
...
__ garments take 50cm of space: equal to one rail.

Fill in the blank.
And then divide 200 by that number, to get the number of rails you will need.
