Answer & Step-by-step explanation:

Assuming that there is a constant rate of change, we can use the equation:


y=kx

k is the constant rate of change. Set up an equation in which the pounds are determined by the rate of change between kilograms and pounds:


1=k(2.2)

Isolate the variable k:


(1)/(2.2)=(k(2.2))/(2.2)\\\\(1)/(2.2)=k

Set up another equation like so:


(y)/(x)=(y)/(x)

Insert values:


(1)/(2.2)=(y)/(112)

Solve for y. Cross multiply:


1(112)=2.2y\\\\112=2.2y

Isolate the variable. Divide both sides by 2.2:


(112)/(2.2)=(2.2y)/(2.2) \\\\ y=50.9090...

So, there are about 50.9 kilograms in 112 pounds.

:Done
