\[\frac{ 3 }{ m }4+\frac{ 1 }{ 3(m4) }=\frac{ 6 }{ m }\]is it like this?

yes! @Linyu I just need to know how to do it, my book doesn't give an example for ones like this

you need to convert the denominators to the same form\[\frac{ a }{ b }+\frac{ c }{ d }=\frac{ ad }{ bd }+\frac{ cb }{ bd }\]

\[\frac{ 3 }{ m }\frac{ 4 }{ 1 }+\frac{ 1 }{ 3(m4) }=\frac{ 6 }{ m }\] convert the denominator into 3m(m4) we have\[\frac{ 3(m4) }{ 3(m4) }\times \frac{ 3 }{ m }\frac{ 3m(m4) }{ 3m(m4) }\times \frac{ 4 }{ 1 }+\frac{ m }{ m }\frac{ 1 }{ 3(m4) }=\frac{ 3(m4) }{ 3(m4) }\times \frac{ 6 }{ m }\]

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

the problem should be \[\frac{ 3 }{ m4 }+\frac{ 1 }{ 3(m4) }=\frac{ 6 }{m? }\]

Oh! that will be better to solve

yes! so I think the answer is 10/m4 @Linyu

3m(3)+m=3(m4)(6) 9m+m=18m72 10m=18m72 0=8m72 72=8m m=72/8 m=9
