May-Brith, learning to read fractions is not difficult. A standard measure is one inch. As you look at your tape measure you will see lines at each inch mark. Between these lines you will see lines of different lengths. You will notice that the longest line is right in the middle. This is a half inch (1/2") mark, it takes two of these divisions to make one inch. The next longest line lies between the 1/2" mark and the one inch mark. It takes 4 of these divisions to make one inch. This is a quarter inch (1/4") mark. In woodworking we also use the 1/8" and 1/16" measurements on a regular basis, sometimes 1/32". These lines are progressively shorter on your tape measure. Just remember that the bottom number is how many of the divisions will add up to one inch. The top number is how many of these divisions you need for your measurement. To find the decimal equivelent of a fraction think metric, with one inch being 1000 units of measurement. 1/2" = .500", 1/4" = .250", 1/8" = .125" and so on. Let me know if this helps.
