at a barbecue to celebrate the end of the soccer season 1354 hotdogs were served round the number of hotdogs to the nearest ten I let me just rewrite the number 1,350 for now let's just remember our places this is the I can write like that this is the ones this is the tens this is the hundreds place and this is the thousands place now they want the round the number of hotdogs to the nearest ten so round it to the nearest ten here and so right now we have five tens but in order to round we have to look to the next smallest place so we'll look to the ones and we have four ones here and so because this number is less than five so because this is less than 5 we round down so less than five so we're going to round down if you round down to the if you round down you get two exactly five tens or you say 1,350 we have rounded to the nearest ten 1,350 hotdogs let's do another one so here we're told the intendant's at a local basketball game was eight thousand six hundred forty three be bowl round the attendance to the nearest hundred and like always pause this video and see if you can figure that out let's see eight thousand six hundred and forty three we want to round to the nearest hundred so we go one place to the right of that and we say okay is this greater than or less than is this less than five or greater than or equal to five since it is less than five so this is less than five so because of that we round down and so we were going to round down to eight thousand six hundred so we have rounded to the nearest hundred eight thousand six hundred people let's do one more the city of joy Ville has eighty-seven thousand three hundred eighty-eight round the number of people who live in joy Ville to the nearest thousand so we have eighty-seven thousand three hundred and eighty-eight we want to round to the nearest thousand so once again we go one place to the right we see that it is less than five and so we're going to round down we are going to round down to eighty-seven thousand that is the nearest thousand eighty-seven thousand now since all of the examples we ended up rounding down let me just show you what would have happened when we round up if we had it was eighty-seven thousand five hundred and eighty-eight well once again we are rounding to the nearest thousand you go one place to the right and say hey this is five or larger so in this case you would round up so you would round the thousands up to eighty eight thousand in this situation so you go one space to the right one place value to the right if that is less than five then you round down if it is 5 or greater you round up
