Question

Solve for z. 4/z =12/5

Answer 1

$\dfrac{4}{z}=\dfrac{12}{5}\\\\ 12z=20\\\\ z=\dfrac{20}{12}=\dfrac{5}{3}$

Answer 2

Step 1: 4/z = 12/5 (original question)

Step 2(cross-multiply): 4(5) = z(12)

Step 3: 20 = z(12)

Step 4: 20 = 12z

Step 5: 12 = 20

Step 6: Divide both sides by 12.

Step 7: z = 20/12

Step 7(reduce the fraction): z = 3/5 <<<Answer
