DAV Class 4 Maths Chapter 5 Worksheet 2 Notes
Converting Smaller Unit Into Bigger Unit:
1. Converting centimetres into metres and centimetres
we divide the number of centimetre by 100 to convert ‘centimetres’ into ‘metres’.
E.g. 1100 cm = 1100 ÷ 100 m
= 11 m
2. Converting metres into kilometres and metres
we divide the number of metres by 1000 to convert ‘metres’ into ‘kilometres’.
E.g. 6094 m = 6094 ÷ 1000 km
= 6 km 94 m
