Cm=centimetres
Mm=millimetres
1 meter=100 centimeters
1 meter=1,000 millimeters
So to solve your equation, you divide 140 by 100cm (since he is measured in centimetres)
140cm÷100cm=1.4 meters-is Ben's height
To solve Mike's height, you divide 1090 by 1,000mm (since he is measured in Millimetres)
1,090mm÷1,000mm=1.09 meters-is Mike's height
1.4 meters is greater than 1.09 meters
To see by how much, you subtract 1.4m by 1.09
[tex]1.4-1.09=.31m[/tex]
[tex]1.4>1.09[/tex]
Mike is taller than Mike by .31 meters or 31 in centimetres or 310 in millimetres
