least common denominator
8/9-4/5
What do you think it is?
What can be evenly divided by both 9 and 5?
IS IT 3 OR 1
THE ANSWER I HAVE IS 40/45-36/45
No
I don't think so
Yes, Alexius is right!
40/45 - 36/45 = 4/45
Mark -- please don't answer another student's question unless you are 100% positive your answer is right.
Ms.Sue I get late responses for some reason He said 3 or 1 so I said no. I didn't see the revised response.
4/5 is not 36/45. It is 32/45.
40 = 5*8, not 5*9
