Round a Number to the Nearest Whole Number

Narrator: Round to the nearest whole number 2 and 94 hundredths or 2.94. So in order to round to the nearest whole number we’re looking to the nearest - to our ones place, excuse me, we’re going to round to the ones place and in order to do that we need to look one place to the right at our tenths place and determine if we’re going to round up or down. We know that if we have a 1, 2, 3, or 4, in our tenths place then we will round down and if we have a 5, 6, 7, 8, or 9, we will round up. In this case we have a 9 in the tenths place so that tells us we’re going to round up. If we wanted to look at this on our number line to visually see why we round up on our rounding. This number to the nearest whole number we have 2 [left] our here and 3 [right] over here, we can add our - break this into tenths so we have point 1, point 2, point 3, point 4, point 5, point 6, point 7, point 8, point 9. Now those aren’t perfectly spaced but we can get the idea here so we’re at 2.9 and then we can break this down into hundreds even and we would be right about here [between point 9 and 3 is marked] on our number line. Ok so we’re at 2 and 94 hundredths and just looking at this we can that we can much closer to 3 than we are to 2. So that kind of helps us understand why when we have a 9 in the tenths place we’re going to round up to get to our nearest whole number so the answer to number 4 is 3.
