Question

A shop has a sale of 30% off all items in stock.

If the original price of a dress is £30 what would be its sale price?
​

Answer 1

9

Explanation:

because, 30 (the percentage) /100(over one hundred percent) x 30(the actual price) = 9

Answer 2

I’m not sure if this is correct so sorry if it’s not but this is what I would do :
30%= 3/10 3/10 of 30 is 9 because 30/10=3
3x3=9 30-9=21

Sorry if it’s wrong but have a good day
