Multiply. Use cross reducing to simplify the expression.
3/4 X 5/7 X 14/15 X 8/9
we think we have an answer but are NOT sure at all.
It would be then written as follows: 1/1 X 1/1 X 2/3 X 4/3 = 8/9 would be the newest answer if we did that correct?

simplify the expression.
3/4 X 5/7 X 14/15 X 8/9
----
= (3*5*14*8)/(4*7*15*9)
------
Cancel the common "3" factor
Cancel the common "4" factor:
Cancel the common "5" factor
Cancel the common "7" factor
-------------------------------
= (1*1*2*2)/(1*1*3*3)
-------
= 4/9
