ANSWER
1480.8 is greater than 15.1

We want to find which number is greater between 15.1 and 1480.8
We see that the highest place value in the number 15.1 is Tens, i.e.:
T U Tnth
1 5 . 1
While in 1480.8, the highest place value is Thousands, i.e.:
T H T U Tnth

Since Thousands is greater than Tens, we see that 1480.8 is greater than 15.1
