Full solution

Q. Solve for z z .\newlinez12=45z= \begin{array}{l} \frac{z}{12}=\frac{4}{5} \\ z= \end{array}
  1. Identify equation: Identify the equation to solve for zz. We have the equation z12=45\frac{z}{12} = \frac{4}{5}.
  2. Solve for zz: Solve for zz by cross-multiplying to get rid of the fractions.\newlineMultiply both sides of the equation by 1212 to isolate zz.\newlinez=45×12z = \frac{4}{5} \times 12
  3. Cross-multiply: Perform the multiplication to find the value of zz.z=4×125z = \frac{4 \times 12}{5}z=485z = \frac{48}{5}
  4. Perform multiplication: Simplify the fraction to get the final value of zz.z=9.6z = 9.6
