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
