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

= $\frac{80}{220}$

= $\frac{80 \div 20}{220 \div 20}$ (HCF of 80 and 220 = 20)

= $\frac{4}{11}$

= 4 : 11

Thus, the ratio of the length of the red ribbon to that of the blue ribbon is $\frac{4}{11}$ or 4 : 11.
