What are the ratio and proportion?
The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
01) The First case
Amount in one can = 4.5 ounce
Number of cans = 6
Amount in all 6 cans = 6 × 4.5 = 27 ounces.
The price per ounce = 7.07/27 = $0.26
02) The second case
Amount in one can = 5.5 ounce
Number of cans = 4
Amount in all 4 cans = 4 × 5.5 = 22 ounces.
The price per ounce = 6.60/22 = $0.30
03)The third case
Amount in one can = 3.5 ounce
Number of cans = 5
Amount in all 5 cans = 5 × 3.5 = 17.5 ounces.
The price per ounce = 4.20/17.5 = $0.24
The least price per ounce is $0.24 so the third case is the best to buy.
Hence "The package that is the best to buy will give the highest amount in less money will the store sells 3.5 -ounce cans in packages 5 of cans for $4.20".
