Question

A rope of length 3m 60 cm is cut into two pieces such that the ratio of the lengths of the pieces is 7:5 . Find the length of the larger piece . Please help me and tell the solution ​

Answer 1

Total length of rope=3m60cm

=360cm

ratio=7:5

let ratio be x

7x + 5x = 360

12x= 360

x=360/12

x =30

smallest part =5x

=5×30

=150cm

largest part = 7x

=7×30

=210 cm

hence, the length of larger piece is 210 cm

Have a good day....!
