b=1/2=0,5 mb=12=0,5m

Explanation:

F_1:" First weight"F1: First weight
F_2:" Second weight"F2: second weight
a:" distance between F_1 and fulcrum"a: distance between F_1 and fulcrum
b:" distance between F_2 and fulcrum"b: distance between F_2 and fulcrum
"you can write balance equation by:"you can write balance equation by:
F_1*a=F_2*bF1a=F2b
5*6=60*b56=60b
cancel(30)=cancel(60)*b
b=1/2=0,5 m
