whats the answer to 1 whole and 1/2 divide by 3/16?

1 whole divided by 3/16 is: 5 1/3

1/2 divided by 3/16 is: 2 2/3

I'm guessing this is what you were asking? The question was a bit unclear.

I think they want to know this :

[ 1 + 1/2 ]  / [3 / 16]   =

[3/2] / [ 3/16]      invert the second fraction and multiply

[ 3/2]  *  [ 16/ 3]      swap denominators

[3 / 3 ]  *  [  16 / 2  ]   =

1 * 8  =

8
