Great Job !
Great colors for the hundred grids..
But next time you should put an explanation for your answer.. here's an example for 14 b) "100 x 4 = 400. I multiplyed 0.75 by 4 and I got 3, So I colored in 3 squares." Well something like that.. but you did a nice job.

Good job John ! your hundredth grids were really colourful. You should really explain your answers in case others dont understand how you got to that place. You might want to bold words or add some colour. Other than that, good job.
