Question

The owner of a dress shop ordered 33 dresses from a new designer. The designer's dresses now make up to 30% of all dresses in the shop. How many dreses are in the shop in all?

Answer 1

30     33
-----= ----
100     ?
To find this we need to find what makes 30 into 33. 33 divided by 30=1.1
To find ? we need to reverse since it's on the other side. 100 x 1.1=110
110 dresses in total.
