Answer 1

Answer:

3:1.

Step-by-step explanation:

There are sold 240 necklaces per month. Of that 240 necklaces, 180 of them are sold online. The question was, what was the ratio of the online sales and shop sales.

KNOWN:

Total Sales (T) = 240 necklaces

Online Sales (O) = 180 necklaces

UNKNOWN

Shop Sales (S) = ?

The ratio of Online Sales and Shop Sales = ?

Solution:

The ratio of the online sales and shop sales = O:S

1. Since we already know the Online Sales, let us find the Shop Sales.
   Total Sales = Online Sales + Shop Sales
   240 necklaces = 180 necklaces + S
   S = 240 necklaces - 180 necklaces
   S = 60 necklaces
   
2. Let's find the ratio of online sales and shop sales.
   The ratio of the online sales and shop sales = O:S
   O:S = 180:60
   They can still be simplified because they are divisible by 60.
   Therefore 180:60 = 3:1
   
3. Take note that in ratio, the order of the mentioned variables is important. Also, always use the simplest form
