CCSS.Math:

## Video transcript

show 109 percent by shading so just as a bit of a review 109 109 percent if we were to write it out would literally be 109 per cent percent which is the same thing as 100 and which is the same thing as 109 per per and I could write cent again but that's getting old cent means 100 so it literally means 109 per hundred per hundred if you had 100 per hundred you're dealing with the whole but now we're have more than a whole we have 109 400 we can actually write this as a ratio or as a fraction this is the same thing as 109 per hundred it's the same thing as 109 over a hundred so let's shade that in so we have a whole here so we could consider this square a whole in the last video we counted there's this is a 10 by 10 square it is cut up into a hundred pieces so if we want 109 of those 100 pieces what are we talking about well that means we're going to shade in all of the hundred right over here let me do that in a new color so we'll shade in all of this we'll shade in all of this right here that would be if you just shaded that in that would be hundred percent that would be a hundred over a hundred or a hundred per hundred or a hundred percent I hope I think you're getting the meaning of all of this here I just want you to just memorize the stuff this really just means a hundred out of 100 or a whole and you can see that this is the whole square that's 100 100 right there the question is saying show us 109 percent by shading so we have to we already did 100 per 100 but we need to do another 9 so let's shade it another 9 so we know we have a 1 2 3 4 5 6 7 8 9 so this piece right here you could almost view that is well that is that is 9 percent that is 9 percent of an entire square this is a hundred percent of an entire square if you consider this whole thing Plus this blue area right over here you are talking about 100 and 9% of this of one whole square hopefully that made sense
