A piece of cable which is 3/5 m long is to be cut into pieces 1/20 m long. How many pieces will there​ be?

4 answers

60 pieces
(3/5) / (1/20) = 12 pieces
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
well, 3/5 = 12/20, so ...
