Answer 1

in primul rand introducem intregii in fractie

asadar

7/2+{1/3 - [ 1010/142- (2636/213-2265/426)]}: 213/17=

7/2+{1/3 - [ 1010/142-(5272/426 - 2265/426)]}: 213/17=

7/2 +[1/3- ( 1010/142 -3007/426)] : 213/17=

7/2 +[1/3- ( 3030/426 - 3007/426)] : 213/17=

7/2+ (1/3 -23/426) : 213/17=

7/2 + (142/426 - 23/426): 213/17=

7/2 + 119/426 : 213/17=

7/2 + 119/426 * 17/213=

7/2 + 2023/90738=

317583/90738 + 2023/90738= 319606/90738= 3 $\frac{47392}{90738}$
