Question

Which is the biggest number?
$0.6$, $0.25$, $0.52$, $0.81$

• A. $0.6$
• B. $0.81$
• C. $0.25$
• D. $0.52$

Answer 1

The correct option is B $0.81$

First, we convert the given decimals into like fractions.

$0.6=0.60=\frac{60}{100}$

$0.25=\frac{25}{100}$

$0.52=\frac{52}{100}$

$0.81=\frac{81}{100}$

Comparing the numerators we get,
$81>60>52>25$.

Now we can write,
$\frac{81}{100}>\frac{60}{100}>\frac{52}{100}>\frac{25}{100}$.

$\therefore 0.81$ is the biggest of all.
