In the following figure, each division represents 1 cm: Express numerically the ratios of the following distances:
(i) AC : AF (ii) AG : AD (iii) BF : AI (iv) CE : DI

(i) 2 : 5 (ii) 2 : 1 (iii) 1 : 2 (iv) 2 : 5
Read positions on the 0–8 cm scale (A=0, B=1, C=2, … , I=8). Compute each distance and reduce to simplest form.
