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!
1 m = 100 cm → 7/10 m = 7/10 x 100 cm = 70 cm
7 km = 7*1000 m = 7*1000*100 cm = 700000 cm

Convert to the same units, drop the units and simplify: 1 yd = 36 in → 7 in : 1 yd = 7 in : 36 yd = 7 : 36
Take the 'reciprocal' of the given scale factor to go the other way. The 'reciprocal' of a number is 1/(the number). 3 ==> 1/3 5 ==> 1/5 1/7 ==> 7 2/3 ==> 3/2 etc.
scale factor=7/3.5=2
if your looking up what the scale factor of 3 over 7 u must be dumb

25 / 175 = 1/7 cm / m = 1 / 100 Total = 1 / 700 ■

There are 1000 millimetres in one metre. Therefore, 7 metres is equal to 7 x 1000 = 7000 millimetres.
