the answer is: each school picked up 12/128 tons

if I get the graph correct, every cross indicate the quantity under it. (an x above 1/8 means that there is 1/8 of a ton collected)

then, we need to add up the total amount of tons they collected.

we have 6 crosses in 1/8, 8 crosses in 1/4 and 2 crosses in 1/2. then we do:


6\cdot(1)/(8)=(6)/(8)=(3)/(4)
8\cdot(1)/(4)=(8)/(4)=2
2\cdot(1)/(2)=1

we add everithing:


(3)/(4)+2+1=3+(3)/(4)=(12)/(4)+(3)/(4)=(15)/(4)

the total amount of trash collected is 15/4 tons (3.75 tons)

there are 32 schools, then we need to divide the amount of trash by the amount of schools:


(15)/(4)/32=(15)/(4)\cdot(1)/(32)=(15)/(4\cdot32)=(15)/(128)

every school got 15/128 tons of trash
