Best ResponseYou've already chosen the best response.1\[\frac{ 3 }{ m }4+\frac{ 1 }{ 3(m4) }=\frac{ 6 }{ m }\]is it like this?

Best ResponseYou've already chosen the best response.0yes! @Linyu I just need to know how to do it, my book doesn't give an example for ones like this

Best ResponseYou've already chosen the best response.1you need to convert the denominators to the same form\[\frac{ a }{ b }+\frac{ c }{ d }=\frac{ ad }{ bd }+\frac{ cb }{ bd }\]

Best ResponseYou've already chosen the best response.1\[\frac{ 3 }{ m }\frac{ 4 }{ 1 }+\frac{ 1 }{ 3(m4) }=\frac{ 6 }{ m }\] convert the denominator into 3m(m4) we have\[\frac{ 3(m4) }{ 3(m4) }\times \frac{ 3 }{ m }\frac{ 3m(m4) }{ 3m(m4) }\times \frac{ 4 }{ 1 }+\frac{ m }{ m }\frac{ 1 }{ 3(m4) }=\frac{ 3(m4) }{ 3(m4) }\times \frac{ 6 }{ m }\]

Best ResponseYou've already chosen the best response.1now all the denominators are the same 3m(m4) so feel free to cancel them out. And you'll get\[3(m4)\times33m(m4)\times4+m=3(m4)\times6\]

Best ResponseYou've already chosen the best response.0the problem should be \[\frac{ 3 }{ m4 }+\frac{ 1 }{ 3(m4) }=\frac{ 6 }{m? }\]

Best ResponseYou've already chosen the best response.0yes! so I think the answer is 10/m4 @Linyu

Best ResponseYou've already chosen the best response.13m(3)+m=3(m4)(6) 9m+m=18m72 10m=18m72 0=8m72 72=8m m=72/8 m=9
