No

Think of money. Which is the largest amount?

81/1%

To arrange the given numbers in descending order, we need to compare them and sort them from largest to smallest. Let's start by converting all the numbers to the same format.

1. 0.8333 - This number is already in decimal form.
2. 4/3 - We can convert this fraction to a decimal by dividing 4 by 3: 4 ÷ 3 = 1.3333.
3. 81.1% - To convert a percentage to a decimal, we divide by 100. So, 81.1% becomes 81.1 ÷ 100 = 0.811.

Now that we have converted all the numbers to decimal form, let's arrange them in descending order:

1. 1.3333
2. 0.8333
3. 0.811

Therefore, the numbers in descending order are: 1.3333, 0.8333, 0.811.
