Dividing a decimal by a whole number on the number line


Video transcript

in this video we're going to try to figure out what 0.6 or 6 tenths divided by 2 is and I'll give you a little bit of a hint we have 6/10 plotted on the number line right over here and so one way to think about it is if I wanted to go from 0 to 6 tenths in two jumps how big would each of those jumps have to be pause this video and try to figure that out on your own before we work through it together alright so as I mentioned one way to think about it is how can I go from 0 to 6 tenths in 2 jumps to equal jumps I should say well if we just eyeball it right over here I could do one jump like that and then another jump like that so I did one jump and then two jumps and so one way to think about it is we've had we've divided 6 tenths into two jumps and each of those jumps are how far well each of those jumps are 1 2 3 tenths so this is three tenths or I could write it like this 3 tenths we have another one to three tenths so this is going to be equal to three tenths and we've thought about it in other ways if you have six of something and you divide it by two you're going to have two groups of three of that something so if you have six tenths and you want to put it into two equal groups well each of those groups are going to be three tenths
