Answer:
Step-by-step explanation:
A jewellery shop sells 240 necklaces a month.
180 of the necklaces were sold via the shops website the rest were sold in a high street shop. This means that the amount that were sold in the shop would be the total amount sold for the month minus the amount that were sold via the shop's website. It becomes
240 - 180 = 60
The ratio of online sales to shop sales would be the number of necklaces sold online / the number of necklaces sold in the shop. It becomes
180/ 60 = 3/1 = 3
