first, turn put them into rational form 86/9 - 41/6 If you work these out, you'll see that 86/9 is equivalent to 9 5/9 and 41/6 is equivalent to 6 5/6

so the answer is 6 5/6

I got these numbers by multiplying the 9 by the 9 in the denominator, adding the five from the numerator, and then putting that answer once again over the original denominator (in this case 9). I went through the same steps to get 41/6.

Then you need to find a common denominator between them so that you can subtract. Can you do that?

no i need help

Ok, so you have 86/9- 41/6. Do you understand how I got that?

  • anonymous
you used 9 to multiply the denominator

Yes, because what 86/9 means is "how many times will 9 go into 86?" The answer is that it goes 9 times with 5 / 9 left over. |dw:1327381866774:dw|

So all you're doing is reversing things so that you go from the answer 9 5/9 back to the question "how many times does 9 go into 86", or 86/9

After you've done the process with 9 5/9 you get 86/9. After you do it with 6 5/6 you get 41/6. But you're not done yet!

Cinar is showing you another way to do it, that might give you smaller numbers to work with.
