A number of hotels are ranked based on various factors, each with a different weight.
This is the rating and weights for the hotel "The Swan Inn":
What is the hotel's overall rating?
In order to determine the hotel rating, we will calculate an average.
Let's remember the weighted average formula:
(value A X weight percentage A)+(value B X weight percentage B)...

Let's solve the multiplication problems first:
We'll add them together and get: 3.475 and that's the hotel rating

Norbert buys some new clothes.
When he gets home, he decides to work out how much each outfit cost him on average.
What answer should he come up with?
Percentages represent parts of 100, so 45% means 45 out of 100, or 0.45. If you multiply by 45 instead of 0.45, your answer will be 100 times too big!
Add up all the weight percentages - they should equal 100%. In this problem: 45% + 30% + 10% + 10% + 5% = 100% ✓
Check your decimal conversions! Your weighted average should be between the lowest and highest individual ratings. Here, it should be between 1 and 4.5.
