Question

Which is greater?
$1.23$ or $1.2$

Answer 1

consider the place value of the digits

$1.23=1\frac{2}{10}+\frac{3}{10}$

$1.23=1\frac{20}{100}+\frac{3}{100}=1\frac{23}{100}$

$1.2=1\frac{2}{10}=1\frac{20}{100}=1\frac{20}{100}$

$1.23$ is larger by $\frac{3}{100}$

$1.23$ is greater than $1.2$

as

$1.23-1.2=0.03$

$\therefore 1.23>1.2$
