To
determine the z in this proportional equation. We used first understand the
formula and equation by understanding the relationships between z, x and y then
we apply the values or numbers and undergo the process of finding the asked
unknown value.
1.
Since z is directly proportional to x and
inversely proportional with Y. we have the equation set as: Z = X / Y
2.
Hence if the given values of X = 12, and Y = 23. Then apply the
values in the formula we have:
a.
Z
= X / Y
b.
Z
= 12 / 23
c.
Z
= 0.522
