Identifying tenths on a number line


Video transcript

where is the point on the number line well here it is here's the point but I'm guessing that they're asking not literally just to find it and look at it but what number is this point graphed at where is this on the number line so one thing we know pretty quickly is the number is between 3 & 4 it's greater than 3 but it's not quite 4 but to figure out how much greater than 3 we need to know what these black tick marks represent so between 3 & 4 there's 1 2 3 4 5 6 7 8 9 10 equal spaces so each of these distances each of these equal spaces is one tenth or one tenth of the distance between 3 & 4 is one out of ten equal spaces so if that's one tenth and this next space is another one tenth and then we have to travel one more tenth to get to our point so we went three we know it's 3 plus 1 2 3 tenths 3 & 3 tenths or let's write this as a decimal let's look at it as a decimal if we wanted we could have our ones place value and then after the ones the decimal and the tenths so for the ones there's three ones and how many tenths did we see here there were three tenths so either way we can say 3 & 3 tenths or 3 & 3 tenths our decimal our point is 3 point 3 on the number line
