Fractions can't be added or subtracted if they don't have the same denominator. It doesn't have to be the least one, but they both have to be the same one. ... I can't think of a reason "why" that's short enough to type on an Android keyboard, but I'll give you this to think about: If I asked you to add 1/2. and. 1/5, and you didn't want to bother finding a common denominator, then what WOULD you use for a denominator for the sum ? ?
The proportional relationship that represents the market that sells their carrots at a lower rate per pound is: y = 1.6x.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
From the table, the rate is:
k = $8.8/4.4 = 2.
From the market, the rate is:
k = $4.8/3 = $1.6.
Hence the equation is y = 1.6x.
