How to Solve Proportional’s

Problem:

Find the constant of proportionality.

Z is directly proportional to t. If t = 8, than z = 84. Solve for k.

The first thing you want to do to solve for k is to write the formula to solve for.

Z=KT

The second thing you want to do to solve for k is to fill into the formula the T=8 and Z=64.

64=K*8

How to Solve Proportional’s

The next step is to divide both sides by 8 to isolate the K. In this step the 8’s on the right side of the equation will cancel each other out.

64=K*88 8

How to Solve Proportional’s

This step you will complete the problem by dividing 64 by 8.

64=K 8

Answer is:8=K
