Question

The total weight of 8 onions is 720 grams. What is their average weight?

Answer 1

The average weight is `90` grams.

Explanation:

To find an average you need to find the total weight and know how many are in the set.
`"Average" = "total weight"/ "amount"`

In this problem they give you the total weight already of 720. Now all you need to do is divide by the amount of onions, 8

`"Average" = 720/ 8`

If you don't have a calculator handy...remember to ignore the zero an just divide `72` by `8` and you get `9`.

Then add the `0` to the end of your answer to get `90` grams.
