To solve for m in the equation (m + 12) / m = 8, we can start by multiplying both sides of the equation by m to eliminate the denominator on the left-hand side:
(m + 12) / m = 8
m(m + 12) / m = 8m
m + 12 = 8m
Next, we can simplify by subtracting m from both sides:
m + 12 - m = 8m - m
12 = 7m
Finally, we can solve for m by dividing both sides by 7:
12 / 7 = m
Therefore, the solution to the equation (m + 12) / m = 8 is m = 12/7 or approximately 1.71 (rounded to two decimal places).
