बेरीज

उत्तर

`2 3/4 - [3 1/8 div {5 - (4 2/3 - 11/12)}]`


`= 11/4 - [25/8 div {5 - (14/3 - 11/12)}]`


`= 11/4 - [25/8 div {5 - ((56 - 11)/12)}]`


`= 11/4 - [25/8 div {5 - 45/12}]`


`= 11/4 - [25/8 div {(60 - 45)/12}]`


`= 11/4 - [25/8 div 15/12] = 11/4 - [25/8 xx 12/15]`


`= 11/4 - 5/2 = (11 - 10)/ 4 = 1/4`
