It takes Maria 11 mins to weed a garden. Mike can weed the same garden in 10 minutes. How long would it take them if they work together?  I got 21 mins but i honestly don't know how to round it.

Best ResponseYou've already chosen the best response.0then i would multiply the 1 and that would isolate the x. leaving me with the 21/110 and then i simplify it?

Best ResponseYou've already chosen the best response.1See this, \[\frac{ 1 }{ a }=\frac{ 11 }{ 10 }\] \[a=\frac{ 10 }{ 11 }\]
