All you need to do is first make 25% into 25 over 100 or 25/100 then you divide which will give you 0.25 next you're gonna have to divide 375 by 0.25 which is 1,500. Then for B it do it again 60% to 60/100 next turn it into a decimal which is 0.60 or 0.6 then multiply 375 by 0.6 which is 225 then subtract 375 by 225 then you got the final answer:150. I hope I helped you
