Solution
Length of red ribbon = 80 cm
Length of blue ribbon = 2.20 m = 2.20 × 100 = 220 cm
∴ Ratio of the length of the red ribbon to that of the blue ribbon = Length of red ribbon : Length of blue ribbon
= 80 cm : 2.20 m
= 80 cm : 220 cm
= `80/220`
= `(80 div 20)/(220 div 20)` (HCF of 80 and 220 = 20)
= `4/11`
= 4 : 11
Thus, the ratio of the length of the red ribbon to that of the blue ribbon is `4/11` or 4 : 11.
