4.Look carefully at these sums:
Example: How many cm are there in 25mm and how
many millimetres are there left over?
25mm = 10mm + 10mm + 5mm
= 1cm + 1cm + 5mm
= 2cm 5mm
a)Complete the following:
•37mm = ................................................. cm 7mm
•43mm = 4cm ................................................. mm
•74mm = ................................................. cm ................................................. mm
•100mm = ................................................. cm ................................................. mm
•125mm = ................................................. cm ................................................. mm
•108mm = ................................................. cm ................................................. mm
We use a comma to separate the number of cm from the number of mm.
b)Convert the following into cm:
•3cm 7mm = ................................................. cm
•6cm 1mm = ................................................. cm
•8cm 9mm = ................................................. cm
•72mm = ................................................. cm
•96mm = ................................................. cm
•100mm = ................................................. cm
•104mm = ................................................. cm
•118mm = ................................................. cm
c) Convert the following into mm:
•3cm 4mm = ................................................. mm
•7cm 3mm = ................................................. mm
•8cm 8mm = ................................................. mm
•10cm 7mm = ................................................. mm
•5cm 9mm = ................................................. mm
•12cm 2mm = ................................................. mm
