a mere eight two-thirds of a piece of red licorice so let's draw a piece of red licorice over here and let's draw it into thirds so split it into thirds three equal sections as best as I can draw that and he ate two thirds of it so that's one-third right over here and then this is a second third so that's two thirds what I shaded in this is how much of that red licorice you would have eaten then they tell us Nico ate two-thirds of a longer but equally thick piece of red licorice so it's going to be equally thick but it's longer so I'm just going to draw something that is longer so that's longer but equally thick and he also ate two thirds of this but this is a longer piece it's equally thick so it's actually going to be just a larger piece it's going to have more licorice in it so two thirds of that let me see if I can split this into thirds and then this is one-third this is a second third well two thirds of a larger piece is going to be two is going to be more than two thirds of a smaller piece this right over here this amount that he ate it has the same width but it's longer than this right over here so Nikko because this is a longer but equally thick piece of red licorice Nikko ate more red licorice Nikko for Shore let's do another one my unicorn that's interesting to have a unicorn my unicorn hate 2/6 of a pizza from store a alright I ate 2/6 of a different pizza from store B who ate more pizza well it depends you know stories Pizza might look like this store Arby's Pizza might look like this so if this was the case so if this is store a and this is store B you eat 2/6 of this let me divide this into 6 so that's halves that would be then 6 whoops I want to do 8 so I'm going to do sixths so I want to do something so that's close enough you get the idea so 2/6 would be like this 1/6 2/6 and 2/6 of this would be would be like this let me do my best shot at drawing this I'm trying to do six equal pieces it's hard to hand draw but this gets us close to six here would be that and that and if so store B's pizza is bigger than the store s pizza then I would have eaten more pizza than my unicorn but it might have been the other way around maybe store B's pizzas like this and store A's pizzas like this and if this was the case of my unicorn ate this 2/6 and the unicorn ate more or maybe the pizzas were both this size in which case we would have eaten the same amount so just based on what they told us we don't know how store B speed the compares to store a's pizza we don't know we don't know whether i or my unicorn got more got more pizza let's do one more of these these are fun it took hero 1/3 of an hour to run from his house to school it took Fred 1/3 of an hour to run from his house to school who took more time running to school now this is a good one this is a good one because at first you might say ok you know hero might live here that's Hiro's house I'll put H for hero here maybe this is the school I'll just try to a larger larger building right here this is the school and you might say okay well maybe Fred's house who knows where Fred's house is Fred's house could be here it could be it could be there it could be over here someplace it could be over here someplace we don't know where Fred's house is we we don't know if it's closer or further away for then hero's house you might be saying oh we don't know we remember they're not saying whose house is closer or further away or even who ran faster they're telling us who took more time running to school and they directly tell us the amount of time they took hero took 1/3 of an hour to run to school from his house to school and Fred took exactly 1/3 of an hour I don't know who ran faster or slower who went further distance or shorter distance but I know that they both took the same amount of time they both took 1/3 an hour so this is the same they both took the same same time this question is a little bit like the the famous brain teaser that some people might ask you what weighs more a pound of gold or a pot or what would you rather have or actually known well we I know what you wanted you'd rather have which one weighs more a pound of gold or a pound of cotton and people like Oh Gold is heavier than cotton maybe gold would me but we're saying a pound of gold versus a pound of cotton well they're both a pound they would weigh the same that's kind of what we're doing in this question right over here
