(90+1/88)*1/89
(90+1/88)*1/89
=(89+1+1/88)*1/88
=(89+89/88)*1/89
=89*1/89+89/88*1*89
=1+1/88
=1又88分之1
(90+1/88)*1/89
=(89+1+1/88)*1/89
=(89+89/88)*1/89
=89*1/89+89/88*1/89
=1+1/88
=89/88
(90+1/88)/89
=[(89+1)+1/(89-1)]/89
=[(89^2-1)+1]/88/89
=89^2/88/89
=89/88
(90*88+1)/88*1/89=((89+1)(89-1)+1)/88*1/89
=(89*89-1+1)/88*1/89
=89*89/88*1/89=89/88
