Question

Jada and lin are comparing inches and feet. Jada says that the constant of proportionality is 12. Lin says it is 1/12

Answer 1

Jada compared ratio of feet to inches while Lin compared ratio of inches to feet.

Explanation:

Let

Inches = x

Feet = y

Constant of proportionality = k

ratio of feet to inches

x = ky

1 feet = 12 inches

12 = k * 1

k = 12/1

k = 12

Ratio of inches to feet.

y = kx

1 = k * 12

k = 1/12

Jada compared ratio of feet to inches while Lin compared ratio of inches to feet.
