Compare Two Decimals: Finding the Larger Number

Let's first convert the decimal numbers into simple fractions and compare them:

0.5 is divided by 10 because there is only one number after the decimal point, therefore:

$0.5=\frac{5}{10}$

0.55 is divided by 100 because there are two numbers after the decimal point, therefore:

$0.55=\frac{55}{100}$

Let's now compare the numbers:

\frac{55}{100}>\frac{5}{10}

Therefore, the larger number is 0.55.
