anonymous · Answer

its self explanatory though..just pay closer look to the figure, first write down numbers like that , take common facor and go on reducing...like whats common between 10, 15 it's 5 divide each number by 5, what have u got now , 2 and 3 what common in 2 and 3 nothing so divide either by 2 or 3, then 3 is left divide by three then.....the aim is to reduce left side as well as right side to one
