Question

The price of oil recently went from $7.80 to$10.40 per case of quarts. Find the ratio of the increase in price to the original price.

Answer 1

Hello,

When you are looking for a ratio, it is simply a fraction.

In the numerator, we will put the amount of the increase which is 10.4 - 7.80 = 2.6.
In the denominator, we will put the original price of $7.80.

This gives us the ration of 2.6/7.8 or just 0.33 if we divide.
We can say there was a 33% increase (or one-third).


I hope this helps, Good luck!
