Question: I was taking a practice aptitude test to get myself prepared for the real one and didn't really get stuck on anything except this question. I know the answer (2hrs 24mins), but for some reason I still can't figure out how to solve a problem like this. Please, can anyone solve this properly and explain it to me as ridiculously dumbed down as tolerable? I would greatly appreciate the help... it's driving me nuts...I can usually hold my own when it comes to math problems but now my confidence is gone completely. I need help! Oh and I had to break the question down to get it to fit. Here it is in its entirety: If Sally can paint a house in 4 hours, and John can paint the same house in 6 hours, how long will it take for both of them to paint the house together? AHH HA HA! Okay, nice! I get it now... THANKS!!! Math-magicianry... It always seems so simple after you find out how it's done!

I used to have trouble with these as well... What I do is take the numbers and turn them in to rates. J paints 1 house in 6hrs, that means he paints 1house/6hrs or 1/6 houses/hr S paints 1 house in 4hrs, meaning that she paints 1house/4hrs or 1/4 houses/hr Now try using the rates to write an expression... For J, (1/6)(X) = 1house, X = 6hrs For S, (1/4)(X) = 1house, X = 4hrs Now you want to know how long it takes them to paint 1 house together. For J and S, (1/6)(X) + (1/4)(X) = 1house Simplify (10/24)(X) = 1house X = 24/10hrs or 2.4hrs or 2hrs and 24mins

Wrong section, In this section you need actual data to back up your claims, you want Mythology and Folklore : http://answers.yahoo.com/dir/;_ylt=AoZz2... Food / Other http://answers.yahoo.com/dir/;_ylt=Asg8u... Medicine / Healthcare http://answers.yahoo.com/dir/;_ylt=AvoxA...

Go the basics, the UNITS. If S paint in 4 hs, 1/4 of the house is made in one hour If J paint in 6 hs, 1/6 of the house is made in one hour So in ONE hour they do together 1/4 + 1/6 = 5/12 of the house Now apply a rule of three: 1 Hr --- 5/12 x Hr --- 1 Solution: 12/5 hs. to finish the house = 2.4 hours (0.4 hs = 24 min)

What people fail to understand is that the people in Washington who have all the power, don't care what we want. It's only what they want, that matters. However, in this particular case, I agree with Mitch, because he knows exactly what the art of the deal is which is "No Compromise on the wall".

No, it doesn't work that way. If the Senate changes a bill passed by the House it has to be sent back to the House for approval of the changes. Once they both agree on the same wording it is sent to the President. McConnell would have loved to have a vote taken on the House bill but Schumer and the democrats used the rules to prevent the vote from being taken. Why would he do that unless he knew the bill would pass if the vote was taken. Is that democracy?
