what expression can be used to show dividing 18 boxes into two equal stacks find the expression three times using different ways to write division find the value of the expression so let's just little do this top part right here we have 18 boxes and we divide want to divide them into two equal stacks so we want to divide 18 by two and the way we would write this we'll think a little bit more about what this means we could write this as 18 over 2 this means 18 divided by 2 we could write it as 18 we could write it as 18 divided by 2 just like that or we could write it as 18 18 divided by divided by 2 now before we evaluate it they say find the value of the expression let's think about what this means we have 18 boxes and we want to divide them into two equal stacks let me draw 18 boxes so I have 1 2 3 4 5 6 7 8 9 10 11 12 almost there 13 14 15 16 17 18 so those are my 18 boxes and I divide them into two equal stacks or two equal groups so if I want to make if I want to divide these into two different groups that have the same number of boxes I could just eyeball it and say well let me put one of let's make these top ones one group let's make that one of the groups and let's make these bottom ones let's make these bottom ones another group and these are equal groups how many do we have in each group on the top one we have one two three four five six seven eight nine and in the bottom one we have one two three four five six seven eight nine so we were split it into two groups of nine so 18 divided into two equal groups is equal to is equal to 9 or 18 divided by 2 is equal to 9 or 2 goes into 18 nine times
