Best ResponseYou've already chosen the best response.0when u add fractions, u cant really add across until u find a common denominator. so (7/20)+(1/5), to get a common denominator, u can just multiply 5*4 to get 20, then u would have to multiply 4 with the number at the top, which is 1. so u get (7/20)+(4/20), u have a common denominator now, so u can just add across, 7+4=11, and u dont ever really add denominators together bc they are the same

Best ResponseYou've already chosen the best response.0:), Yes it does! You do it the old fashion way, when a negative number turns into a positive and, negative turns into postive. You see i have a math test tomorrow so I wanna see if i was doing it right! hahaa
