Steps for reading a scale:
Example: scale 0–500g, 5 divisions = each division = 100g
Converting mixed units to a single unit:
3 km 400 m = 3.4 km = 3400 m
2 kg 250 g = 2.25 kg = 2250 g
1 litre 350 ml = 1.35 litres = 1350 ml
Convert 3.5 km to metres.
A bag weighs 2 kg 750 g. Write this in grams.
A bottle holds 1.5 litres. How many ml is that?
Add 1 km 300 m and 2 km 850 m. Give answer in km and m.
Scale: 0 to g, with divisions.
Pointer is at division from 0.
