First you set up the equation as \[\frac{ 1 }{ 10 } + \frac{ 1 }{ 15 } \] =T

Then you add the two fractions i would make the denominator 30 since that would be the easiest \[\frac{ 3 }{ 10 } + \frac{ 2 }{ 30 }\]

After adding that it should look like this \[\frac{ 5 }{ 30 }=\frac{ 1 }{ t }\] then flip both so it becomes \[\frac{ 30 }{ 5 } = t\] then solve and you should get your answer also sorry i made a mistake earlier when i put it equaled to t on the first one, it should have been 1/t
