1/3 of 1/4 is the same as 2/6 of 2/8 (easier for me this way) 2/6 is 0.33 2/8 is 0.25 so you are in essence finding roughly 0.8333 that would be equal to the diagram at the bottom right The other question is (i believe) 1/5 of 5/6 1/5 is 0.2, 5/6 is 0.833 another way to do it is to divide 833 by 5 is 166.6 so it would be 0.166 that would (i think) be the top right
