#1:  214 tickets split 9 ways does not work out to an integer number.  Nobody wants 2/3 of a ticket, right?

So the trick here is to determine the first multiple of 9 greater than 214.

Note that 214/9 = 23.8.  No good.  Not an integer.

Multiply 23 by 9; we get 207.  Multiply 24 by 9; we get 216.  

So, given that we have 214 tickets already, we need 2 more, to make 216.

Check:  Is 216 divisible by 9 without a remainder?  Yes.  Then each of the 9 students will get 24 tickets.

The rest of the problems are somewhat similar to this one.

See whether you can do the next one, #2.

If you'd share your results, I'd be happy to comment on what you've done.

A jar holds no more than 500 buttons. If 5 people bring 330 buttons each, how many jars are necessary to hold all of the buttons
Strike441 [17]

Answer:

We know

1 jar = 500 buttons

5 people bring 330 buttons EACH

We can find/solve by...

people x buttons = total buttons

total buttons / 500 = number of jars needed

So..

5 x 330 = 1650

1650 / 500 = 3.3

Your answer:

4 jars

Explanation

It's impossible to have 3.3 jars, so you must round up.
