Naina was given (1)`1/2` piece of cake and Najma was given (1) `1/3` piece of cake. Findthe total amount of cake was given to both of them.

Answer» amount of cake naina was given = `1 1/2 = 1+1/2 `
`= 2/2+ 1/2 = 3/2`
amount of cake najma was given `1 1/3 = 1+ 1/3`
`= 3/3 + 1/3 = 4/3`
total amount of cake given to both of them = `3/2 + 4/3`
`= (3*3)/6 + (4*2)/6 `
`= 9/6 + 8/6= (12+5)/6 = 17/6 = 2 5/6`piece
