A Jewellery 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 shop sales. Give your answer in its simplest form

Ratio of online sales to shop sales = 3 : 1

Step-by-step explanation:

Total necklace sold in a month = 240

Necklace sold via shop's website = 180

the rest were sold in a high street shop.

Necklace sold via high street shop = Total necklace sold in a month - Necklace sold via shop's website

= 240 - 180

= 60

Necklace sold via high street shop = 60

Ratio of online sales to shop sales

Necklace sold via shop's website : Necklace sold via high street shop = 180 : 60

= 180 / 60

= 3 / 1

= 3 : 1

Ratio of online sales to shop sales = 3 : 1

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
