6.73-2 又8/17+(3.27-1又9/17)
=(6.73+3.27)-(2 又8/17+又9/17)
= 6
7又5/9-(3.8+1又5/9)-1又1/5
= (7又5/9-1又5/9)-(3.8+1又1/5)
= 6-5
= 1
14.15-(7又7/8-6又17/20)-2.125
=(14.15+6.85)-(7.875+2.125)
= 21-10
= 11
13又7/13-(4又1/4+3又7/13)-0.75
= 13又7/13-3又7/13-(4.25+0.75)
= 10-5
= 5
=(6.73+3.27)-(2 又8/17+又9/17)
= 6
7又5/9-(3.8+1又5/9)-1又1/5

= 6-5
= 1
