Mary is buying cups, plates and forks for her party. cups are sold 6 in a package, plates are sold 9 in a package and forks are sold 10 in a package. if she wants to have the same number of each item for her party, what is the smallest number of packeges of each that she should buy?

90

Step-by-step explanation:

So first you got to see what matches with 10 because it is the biggest number

So if you multiply 10x9 you get 90 then you see if you can make a lower

number fit with 6 like halving it. But 10 does not fit with 45 and so doesn't 6 so  

if you also multiply 10x6 you get 60 but 9 doesn't get in so the only lowest

number is 90

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.
