Question

a rope 1.98cm long was cut into parts so that 1 part turned out to be 20% longer than the other part then the lengths​

Answer 1

Answer:

let one part is x cm

then the other part is

x+x.20/100

=x+x/5

=6x/5

so,

x+6x/5=1.98 cm

=> 11x/5=1.98

=> 11x=1.98×5

=> x=1.98×5/11=0.18×5=0.9

so the ither part is 0.9×6/5=5.4/5=1.08

lengths are 1.08 cm and 0.9 cm
