Comparing Decimal Values: Which Number is Larger?

Firstly let's convert the decimal numbers into simple fractions and compare them:

0.25 is divided by 100 because there are two digits after the decimal point, therefore:

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

0.3 is divided by 10 because there is only one digit after the decimal point, therefore:

$0.3=\frac{3}{10}$

Now we can compare the numbers in the numerator:

\frac{25}{100}<\frac{3}{10}

Therefore, the larger number is 0.3.
