Since it's a multiple of 24, it has to be a multiple of the factors of 24.

Factors of 24:
2,3,4,6,8,12

You can use some of this knowledge to help create the number.
Since the # needs to be a multiple off 2, the last digit needs to be an 8

All numbers that are multiples of 3 have the property that all of their digits added together have to be a number that is evenly divisible by 3.

so your number will look like:
_ _ _ _ _ 8

so start trying combinations for the other 5 digits that give you a number that is a multiple of 3: 3,6,9,12,15, ect. If you can't find one, then it's impossible

Which number is the greatest?<br> Select one:<br><br> 10/3<br><br> 7/2<br><br> 9/4<br><br> 17/8
nexus9112 [7]

Answer:

7/2

Step-by-step explanation:

Firstly lets put them all in common denominators (LCM) 3,2,4 and 8 re all divided by 24.

17/8 x 3/3 = 51/24

7/2 x 12/12 = 84/24

9/4 x 6/6=54/24

10/3 x 8/8= 80/24

Now lets see which one is greatest: 7/2 or 84/24

Hope this helps :D
