(11.7-8.4*1又3/10)/ 1又3/10-1/2
=11.7x10/13 -8.4x13/10x13/10-1/2
=9-8.4-0.5
=0.1

1+(6又7/12-3.5)/9
=1+(79/12-7/2)x1/9
=1+(79/12-42/12)x1/9
=1+37/12x1/9
=1+37/108
=1又37/108

95又3/5 * 8.4-95.6*3又2/5
=95.6x8.4-95.6x3.4
=95.6x(8.4-3.4)
=95.6x5
=478

16-1又2/3 * 2又2/5+10.2 / 1/2
=16-5/3x12/5+10.2x2
=16-4+20.4
=32.4
