Answer: Total Length of ribbon is 99 cm

Explanation:

Here ribbon was cut into three parts in the ratio 1:3:5

let x be the common multiple of the above ratio

therefore, the lengths of the three parts of the ribbon is 1x,3x,5x

now, given is that the shortest part i.e 1x is equals to 11cm

i.e 1x=11

x=
(11)/(1)=11cm

now lengths of the ribbon will be

1x=11cm, 3x=3*11=33cm, 5x=5*11=55cm

now total length of piece of ribbon = 1x+3x+5x=9x=9*11=99cm
