## anonymous one year ago The price of oil recently went from $7.80 to$10.40 per case of 12 quarts. Find the ratio of the increase in price to the original price. (type a simplified fraction)

You have as a baseline, 7.80, so that's your denominator The change is price is 7.80 - 10.40 So what they are asking is the ratio of these two quantities: $$\frac{7.80 - 10.40}{7.80}$$
