Convert to same units, then the units cancel and the numbers can (possibly) be simplified:
1 m = 100 cm
→ 7 cm : 1 m
= 7 cm : 1 x 100 cm
= 7 : 100
(cannot be simplified as no common factor other than 1)
If a scale factor of the form 1 : ... is required, then continue by dividing both sides by 7:
7 : 100
→ 1 : 14 2/7
≈ 1 : 14.29

1 km = 100,000 cm so 07 km = 7*100,000 cm = 700,000 cm. Simple!1 km = 100,000 cm so 07 km = 7*100,000 cm = 700,000 cm. Simple!1 km = 100,000 cm so 07 km = 7*100,000 cm = 700,000 cm. Simple!1 km = 100,000 cm so 07 km = 7*100,000 cm = 700,000 cm. Simple!
7 km = 7*1000 m = 7*1000*100 cm = 700000 cm
