Ikr, it annoys me. I can't even get a good answer to my questions either! ITS SO ANNOYING.
In 1 millimeter, there are 0.00109361
So in 2 mm, there are 2 × 0.00109361 = 0.00218722 yards
or do proportions:

=

Cross multiply:
2 × 0.00109361 = y
0.00218711 = y
0.00218722 yards are in 2 millimeters.
Let's say that the number we are looking for is called 'x'.
3 * x = 40
3x = 40
To solve for 'x', we will need to divide both sides by 3.
3x/3 = 40/3
40/3 or 13 1/3 can be multiplied by 3 to get 40.
