You can buy 3 apples at the quick market for $1.05. you can buy 5 of the same apples at stop and save for $2.45. which place is the better buy? [also may you tell me how you got the answer because im struggling with ratios a bit]

Find the price for each apple by dividing the price over the number of apples. At Quixk Market, each apple costs 1.05/3 or $.35 per apple. 
At Stop and Save, you can buy one apple for 2.45/5 or $.49.
The Quick Market is a better buy because It has $.15 less for each apple. 
Hope this helps.

2/1 or just 2. sorry if i get this wrong
