1 4/5 x 1 1/3 x 1 3/4=720/48

Question

then I get 15 not sure it that is correct?

Steve · Answer

1 4/5 = 9/5
1 1/3 = 4/3
1 3/4 = 7/4
multiply it all together and you have

9/5 * 4/3 * 7/4 = 9*4*7 / 5*3*4

9 i 3*3, so you can cancel out 3*4 in both top and bottom, leaving you with

3*7 / 5 = 21/5

How ever did you get 15?
