Divison is the inverse of multiplication. This is another way of looking into division of fractions, expalining the rule of invert and multiply. If 2/3 rd of journey is compelted in 5 hours how long will it take to complete the journey? ie/ 5 /(2/3)

We have to find time for 1/3rd of journey and then add. [br]for 2 parts its is five hours [br]for 1 part its is 2,5 hours[br]total is 5+2,5 hours[br]i.e 5 + 5*1/2 [br]5(1+1/2) [br]5(3/2), whch is excatly invert and mulitply
