（84%/4/5-5/6）*3/5 98*0.2-89*1/5+41*20% 【1-（1/5+2/3）*4/13】/ 11/20

（1/8+1/6）/5/24-2/3*1/4急急急急急急急急急！！！！！！！！！！！！！！

Answer 1

（84%/4/5-5/6）*3/5
=(0.84÷0.8-5/6)x3/5
=(1.05-5/6)x3/5
=1.05x3/5-5/6x3/5
=0.63-0.5
=0.13

98*0.2-89*1/5+41*20%
=98x0.2-89x0.2+41x0.2
=(98-89+41)x0.2
=50x0.2
=10

【1-（1/5+2/3）*4/13】/ 11/20
=(1-13/15x4/13)x20/11
=(1-4/15)x20/11
=11/15x20/11
=4/3

（1/8+1/6）/5/24-2/3*1/4
=7/24x24/5-1/6
=7/5-1/6
=42/30-5/30
=37/30
