Question

Jada and Lin are comparing inches and feet. Jada says that the constant of proportionality is 12. Lin says it is 112.

Answer 1

Answer:

Jada and lin are comparing inches and feet.

Let I denote inches and F denote feet.

It is given that

I =k F or F=m I

So, I/F=k or m=F/I

As  we know 1 feet = 12 inches

constant  of proportionality i.e k=1/12

In case 2, constant of proportionality=12/1=12

So, Jada must have calculated ratio of feet to inches while Lin has calculated the ratio of inches to feet.
