A jewllery shop sells 240 necklaces in a month. 180 of the necklaces were sold via the shop's website, the rest were sold in a high street shop. work out the ratio of online sales to the shop sales. give your answer in its simplest form

If there are 240 necklaces, and 180 necklaces were sold on the website, that means it is 240 - 180. 240 - 180 = 60. This means that 60 were sold in a "high street shop."

Therefore there were

180 online sales

and 60 shop sales.

As a ratio, it is 180 online sales to 60 shop sales. Therefore, the ratio looks like this:

180:60

180:60 = 3:1

3:1 is your answer.
