Why is knowing about rate and proportion and how they function important in real life applications? be specific and give an example of each in your response.

When going shopping, children often look at the prices of various groceries. A parent can easily explain ratios to her child using two different boxes of cereal. For example, if a 10-ounce box of cereal costs $3 and a 20-ounce box of cereal costs $5, the 20 ounce box is the better value because each ounce of cereal is cheaper. This relationship is produced by dividing the number of ounces of cereal by the price. For the smaller box of cereal, each ounce costs 30 cents; for the larger box of cereal, each ounce of cereal costs 25 cents. I hope this helps! :)
