Find the unit rate by dividing price by total units:
0.98 / 4 pints = 0.245 per pint
1.46/ 6 pints = 0.243 per pint
The 6 pint size has a lower price per point so it is the better deal.
To find an improper fraction, you want to do 18* 7 which equals, 126, so then 126+4=130. So then 130/7 would be your answer.
That would be 7 and a half. 7 1/2. You can make seven and a half batches of cookies if the recipe calls for 1 1/3 cups of sugar each and a baker has 10 cups of sugar.
