Question

Solve for c in the proportion.

5/4 = 45/c


c =

Answer 1

To solve the proportion \( \frac{5}{4} = \frac{45}{c} \), you can cross-multiply:

\[
5c = 4 \times 45
\]

Calculating \( 4 \times 45 \):

\[
4 \times 45 = 180
\]

Now, the equation becomes:

\[
5c = 180
\]

Next, divide both sides by 5 to solve for \( c \):

\[
c = \frac{180}{5} = 36
\]

So, the solution is:

\[
c = 36
\]
