Mrs. Cook wants to give each of her 24 students the same amount of candy. If each package of candy has 36 pieces in it, how many packages of candy should she buy so that there will be none left over? 2 3 4 5

mxddi3:

ok, so to start, each pack has 36 pieces, and there are 24 students. What I would do first is take the 36 and multiply it by each answer choice. \[36(2)=?\] \[36(3)=?\] ok so we know that 36*2 is what?

Acolgrove:

72

mxddi3:

yes. so,if she has 24 students, we need to see if 24 goes into 72 an even amount of times. what is 72/24 ?

Acolgrove:

#

Acolgrove:

woops 3

mxddi3:

lol, yes. so, if she buys 2 bags, will each student get the same amount of candy?

Acolgrove:

no

mxddi3:

how so?

Acolgrove:

because 72 divided by 24 was 3

mxddi3:

if she had 72 pieces and you divided that by her 24 students, you got 3. This would mean that each of her students would get 3 pieces of candy.

Acolgrove:

yes

mxddi3:

so if every students gets 3 pieces, aren't they all getting the same amount?

Acolgrove:

yes

mxddi3:

so then the answer is 2 :)

Acolgrove:

why is it 2 and not 3

Acolgrove:

oh nevermind

Acolgrove:

thank you

mxddi3:

lol, you're welcome!
