Ben is 140cm tall. mike is 1090mm tall. who is taller? how much taller?

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





Mike is taller than Mike by .31 meters or 31 in centimetres or 310 in millimetres

The answer simplified would be. -6300x
