Step-by-step solution

First, let's convert the simple fraction into a decimal fraction.

We'll write the number 8 with two zeros in front of it and then add the decimal point:

8100=008. \frac{8}{100}=008.

Since the simple fraction is divided by 100, we'll move the decimal point two places to the left:

008.=0.08 008.=0.08

Let's finally compare our two decimal numbers, focusing on the number after the decimal point:

0.80>0.08 0.80 > 0.08
