Dividing into 9ths will require careful use of the number eight. Find out how to divide into 9ths with help from a high school math tutor in this free video clip.


Hi, I'm Charlie Kasov, and this is how to divide into 9ths. Now, dividing into 9ths is pretty easy, but it's very easy to make a mistake as well. So when you divide into 9ths let's use the number 8. We want to multiply by 1 over 9, if you want to divide this into 9 parts. So 8 over 1 times 1 over 9 is 8 over 9 and we've now divided 8 into 9ths. So 1/9th of 8 is 8 over 9. However, what you have to avoid is if you were to say 8 divided by 1/9th, well the problem when you divide a fraction is you flip and multiply so you'd be multiplying by 9 instead of dividing into 9ths. So I'm Charlie Kasov and you just learned how to divide into 9ths.
