Decimal Comparison: Determining the Greater Value Between Two Numbers

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

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

$0.68=\frac{68}{100}$

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

$0.88=\frac{88}{100}$

Now let's compare the numbers in the numerator:

\frac{88}{100}>\frac{68}{100}

Therefore, the larger number is 0.88.
