Which one is greater?

1 metre 40 centimetres + 60 centimetres or 2.6 metres.

1 metre = 100 centimetre

Now we have 1 metre 40centimetre + 60 centimetre

we have 40 cm + 60 cm =100cm 1metre

∴ we have 1metre + 1metre = 2metres

and the other value is given as 2.6metres

∴ we can see that 2.6metres is greater than 1metre 40centimetre + 60centimetre.
