You can use ratios. Do you know how?

please help on how to use the ratios

Takes 30*20*9 = 5400 hours to do the job

So now u want 40 * 20 * x  = 5400

Define ratios in your own words first, so that I can see that you know what it means?

I am trying to teach you, not just get excited and give out answers like most do so if you don't know the reply to what I ask, then simply tell me.
