That is the same as (3 x 8 x 30) / (4 x 9 x 7)
Which is 720/252 = 20/7 or 2+6/7

3/4 * 8/9 = (3 * 8)/(4 *9) = 24 / 36 = 2/3
4 + 2/7 = 28/7 + 2/7 = 30/7
3/4 * 8/9 * 4 2/7 = 2/3 * 30/7 = (2*30) / (3 * 7) = 60 / 21 =
42/21 + 18/21 = 2 + 6/7

write it out (3/4)(8/9)(30/7)...
now cancel some stuff on top out with some stuff on bottom...
(1/4)(8/3)(30/7) and again.. (1/1)(2/3)(30/7) and again ..
1(2/1)(10/7).. now multiply across the top and bottom...
20/7 and you are done... unless you want to change it to a mixed number... 2 6/7
