No, because if you divide 23 / 4, you get 5.75. You can't get 0.75th of a kid. So it is not reasonable, because it is a decimal, and not a whole number.

Hope this helped! ☺♥

The table shows the ratio of caramel corn to cheddar corn in a bag. What is the constant of proportionality?

Anit [1.1K]

For proportionality constant problems, set up the equation as,

$x=Ky$ ,

Where x and y are the two variables you are comparing and K is the proportionality constant. If we take Caramel Corn values as x and Cheddar Corn values as y, and then solve for K for each ratio lines, we will get the same answer. Let's check.

$15=K(10)\\K=\frac{15}{10}= \frac{3}{2}$ ,

$30=K(20)\\K=\frac{30}{20}= \frac{3}{2}$ , and

$45=K(30)\\K=\frac{45}{30}= \frac{3}{2}$ .

Hence, the proportionality constant, in this case K, is equal to $\frac{3}{2}$ or 1.5. First answer choice is correct.
