Answer:
Given, 1 m 40 cm + 60 cm = 1 m + 40 cm + 60 cm = 1 m + 100 cm We know that, \[1\,cm=\frac{1}{100}m\] \[\therefore \] \[1\text{ }m\text{ }40\text{ }cm+60\text{ }cm\text{ }=1\text{ }m+\frac{100}{100}\text{ }m\] \[=1\,\,m+1\,\,m=2.0\,\,m\]1 On comparing 2.0 m and 2.6 m. We have, \[2.0=2+\frac{0}{10}\] and \[2.6=2+\frac{6}{10}\] Here, whole part of both numbers are same i.e. 2. Now, tenths part of \[2=\frac{0}{10}\] and tenths part of 2.6 \[=\frac{6}{10}\] \[\therefore \] \[\frac{6}{10}>\frac{0}{10}\] Hence, 2.6 is greater than 2.
