So you're saying \[ F = \frac{27.2 m}{t} \] What then are you asking in the first part of the question?

I think you are missing part of the question

@JamesJ yeah that's right and i have to find out the mass using that formula

Ah you need to solve for m. Fine. First, multiply both sides by t and you get \[ Ft = 27.2 m \] Can you solve for m now?

Take Ft = 27.2m and divide both sides by 27.2 and you get ... what?

That can't be right. You didn't divide the left hand side by 27.2 as well. So, we have F = 27.2m/t Ft = 27.2m multiplying both sides by t Ft/27.2 = m dividing both sides by 27.2 Hence \[ m = \frac{Ft}{27.2} \]

Now apply that formula for the second part of the question. You are given values of F and t. Use this formula to find the corresponding values of m.
