we're asked to write this right here in Word form and I'm not saying it out loud because that would give the answer away we have six 3.15 that we want to write in Word form well the stuff to the left of the decimal point is pretty straightforward let me actually color code it so we have six three and then we have a let me do it all in different colors six three and then we have a decimal and then we have a one and A five one and A five now there's really well there's one common way of doing this but we'll talk about the different ways you could express this as a word but we know how to write this stuff to the left this is pretty straightforward this is just 63 so let me write that down so this is 60 63 63 and instead of the decimal will write and and now there's two ways to go here we could say and one tenth and five we could say and one tenth and five hundredths or we could just say look this is 15 hundredths one tenth is ten hundredths so one tenth and five hundredths is 15 hundredths so maybe I could write it like this sixty-three and 15 15 hundredths hundreds hundreds just like that now a it might have been a little bit more natural say how come I don't say one tenth and then five hundredths and you could but that would just make it a little bit harder for someone's brain to process it when you say it so you could have it could have been 63 so let me copy and paste that copy and paste it could be 63 and and then you would write and then you would write 1/10 1/10 for this digit right there and and five hundredths and five hundredths five hundredths 500 s and I think you can appreciate that this is a little bit you know sixty three and one tenth and five hundredths is a hard is hard for most people's brains to process but if say 1500s people get what you're saying this right here let me not to beat a dead horse but this right here this is one tenth right here and then this is five hundredths this is five hundredths five over 100 but if you were to add these two if you were to add one tenth plus 500 so let's do that if you were to add one tenth plus five hundredths plus five hundredths how would you do it well you need a common denominator 100 is divisible by both 10 and 100 so multiply both the numerator and denominator of this character by 10 you get 10 on the top and 100 on the bottom 1/10 is the same thing as 10 over 100 10 hundredths plus 5 hundredths is equal to 15 over 100 so this piece right here is equal to 15 over a hundred and that's why we say 63 and 15 hundredths
