(c) 9 m = ______________ cm (d) 12 m = ______________ cm
Let’s work out
Converting centimetres to metres
1 m = 100 cm
2 m = 2 x 100 cm
To convert cm into m,wendouthowmanytimeswehave100cm.
Example 1: Convert 300 cm into m.
300 cm = 3 x 100 cm
= 3 x 1 m
= 3 m
OR using division
300
100
= 3 m
Example 2: Convert 50 cm into m.
50 cm = m
Example 3: Convert 350 cm into m.
350 cm = 300 cm + 50 cm
= 3 m + m
= 3 m
