1。 Let this score be x/y.

& ltbr & gt& ltbr & gt molecule plus 3 is 5/6, which means (X+3)/Y=5/6.

& ltbr & gt& ltbr & gt molecule minus 3 is 1/3, which means (X-3)/Y= 1/3.

& ltbr & gt& ltbr & gt to solve the equation, X=7, Y= 12, and the score is 7/ 12.

& ltbr & gt& ltbr & gt2。 Let the divisor be x.

& ltbr & gt& ltbr & gt The rest is X-4.

& ltbr & gt& ltbr & gt then X*X+X-4=646.

& ltbr & gt& ltbr & gtX^2+X-650=0

& ltbr & gt& ltbr & gt solve the equation, X=26 or -25, and the answer is 26.
