A student has a daily reading productivity level of 1 chapter while in the computer lab, 5 chapters while at the coffee shop, and 8 chapters while at the library. If 1/12 of the day is spent at a computer lab, 1/4 at a coffee shop, and 2/3 at a library, what is the total daily reading productivity level of the student? Write the solution as a mixed number or a fraction in lowest terms.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
