Hmm... Proportions? well the first thing you need to know about proportions is that is also known as ratios. For example, if you are baking a cake, you might need 3 eggs for every 6 cups of flour. So, you put the 3 eggs as the numerator and the 6 cups of flour as the denominator. Like this
3/6 = 1/2.
This means that for every 1 egg, 2cups of flour is needed. so now you know how many cups of flour to use for 10 eggs.
Next, for you question, Firstly, take $1.90 and divide it by 24, like this
1.90/24 = 0.0791666
this means that for every ounce of pear in the can, it cost exactly $0.079166 cents, Now you compare this with the next value of canned pears which is
2.65/32 = 0.0828125
so, for every ounce of pear in can number 2, cost $0.0828125, so with this, you can see that it cost slightly more for each ounce of pear for the price of 2.65, while it cost less for the canned pears that cost 1.90 for 24 ounces.
So there you have your answer
