That but I need to give it to me linearly such as a/b c/d:/(a). (D)/B:

Certainly! Here's the solution presented in a linear format:

Given the equation:

\[
\frac{4}{5} = \frac{12}{m}
\]

Follow these steps:

1. **Cross-multiply:**
   \[
   4 \times m = 5 \times 12
   \]

2. **Simplify:**
   \[
   4m = 60
   \]

3. **Solve for \(m\):**
   \[
   m = \frac{60}{4} = 15
   \]

So, the final answer is:

\[
m = 15
\]

2. What if the equation was \(\frac{2}{m} = \frac{5}{6}\)? How would the process change?
3. How can you solve for a variable in the denominator, such as in \(\frac{6}{x} = \frac{4}{3}\)?
4. How does cross-multiplication apply to inequalities like \(\frac{a}{b} > \frac{c}{d}\)?
5. Can you rearrange and solve \(\frac{x + 3}{2} = \frac{7}{5}\)?
