[Blindmath] abacus- fractions to decimals

[Shanthala Somayaji]

Dear all,

Is there a method to convert fractions to decimal on Abacus? I have been
using 2 abacii to work out problems like 1/8 =0.125 and manually setting the
numbers without any rules. I apply the rules that apply to  the sighted
method of working out such problems, but feel it is sometimes difficult for
the students to remember. 

Thanks in advance,
Shanthala
