use pictures or diagrams rather than the multiple across rule

2/3 x 1/6=

3/8 x 3/4=

5/6 x 3/3=

1/2 x 3/8=

3/4 x 1 1/2=

Use pictures or Diagrams rather than invert and multiply rule.

2/3/ 6/1=

3/8 / 4/3=

5/6 /3/3=

1/2 / 8/3=

3/4 / 2/3=

2/3 * 1/6

First draw 18 boxes. Choose 2 out of every 3 and that should give you 12.

Next place these 12 next to each other. Divide by 6, in other words count 6 boxes and group them, You get 2

So, required ration = 2/ inital number of boxes = 2/18 = 1/9

3/8*3/4 = 9/32

Take 32 boxes, pick 3 from every 8. Use these to pick 3 from every 4. Number you get to initial is required ratio.

Trick here is to find the LCM of denominator so that you can select integer number of boxes.
