(3/5) / (1/20) = 12 pieces
Bosnian
3 / 5 = 4 ∙ 3 / 4 ∙ 5 = 12 / 20
( 3 / 5 ) / ( 1 / 20 ) = ( 12 / 20 ) / ( 1 / 20 ) = 12
12 pieces.
Check result:
3 / 5 m = 6 / 10 m = 0.6 m
1 / 20 m = 0.05 m
12 ∙ 0.05 m = 0.6 m
( 3 / 5 ) / ( 1 / 20 ) = ( 12 / 20 ) / ( 1 / 20 ) = 12
12 pieces.
Check result:
3 / 5 m = 6 / 10 m = 0.6 m
1 / 20 m = 0.05 m
12 ∙ 0.05 m = 0.6 m

well, 3/5 = 12/20, so ...
