19又5/6+199又5/6+1999又5/6+19999又5/6+2/3怎样简算我简算

19又5/6+199又5/6+1999又5/6+19999又5/6+2/3
=(19又5/6+1/6)+(199又5/6+1/6)+(1999又5/6+1/6)+(19999又5/6+1/6)
=20 + 200 + 2000 + 20000
=22220

=19+199+1999+19999+5/6+5/6+5/6+5/6+4/6
=19+199+1999+19999+24/6
=19+199+1999+19999+1+1+1+1
=(19+1)+(199+1)+(1999+1)+(19999+1)
=20+200+2000+20000
=22220

四个5/6相加得 10/3
19+199+1999+19999 = 20+200+2000+20000 -4 = 22220-4=22216
22216 + 10/3 + 2/3 = 22220

(19+5/6)+(199+5/6)+(1999+5/6)+(19999+5/6)+2/3
=(19+5/6+1/6)+(199+5/6+1/6)+(1999+5/6+1/6)+(19999+5/6+1/6)+2/3
-4/6
=20+200+2000+20000
=22220

19又5/6+199又5/6+1999又5/6+19999又5/6+2/3=19+(5/6)+199+(5/6)+1999+(5/6)+19999+(5/6)+(2/3)=(5/6)*4+(2/3)+19999+1999+199+19=4+19999+1999+199+19=1+19999+1+1999+1+199+1+19=20000+2000+200+20=22220.

把2/3写成四个1/6就可以了
