Step 1: Write down the decimal divided by 1, like this: 0.800/1
Step 2: Multiply both top and bottom by 1000 (it's 1000 bcuz there're 3 decimal places, if there're 2 decimal places you'll multiply the top and bottom with 100)
(0.800/1) x (1000/1000)= 800/1000
Step 3: Simplified it. Notice that both 800 and 1000 can be divided by 200
