Answer 1

1. 41又2/3÷5/3+71又3/4÷7/4+91又4/5÷9/5
=(40+5/3)*3/5+(70+7/4)/7/4+90+9/5/9/5
=24+1+40+1+50+1
=117
2. 1/5×27+3/5×41
=1/5*(27+3*41)
=1/5*(27+123)
=1/5*150
=30
3. 5/11×1/20+3/11×1/2+5/11×1/2
=1/11*(5/20+3/2+5/2)
=1/11*(1/4+6/4+10/4)
=1/11*17*4
=17/44
4. 59又1/2×2/3＋79又1/3×3/4+99又1/4×4/5
=(60-1/2)*2/3+(80-2/3)*3*4+(100-3*4)*4/5
=40-1/3+60-1/2+80-3/5
=180-(1/3+1/2+3/5)
=180-43/30
=178又71/30
5. (11又3/7+7又3/11)÷(5/7+5/11)
=(80/7+80/11)/(90/77)
=80*(7+11)/11*77*90
=16/7
6.1003÷1003又1003/1004+1005÷1006又1/1004
=1003÷(1003+1003/1004)+1005÷(1006+1/1004)
=1+1004+1005/1006+1005*1004
=1005*1005+1005/1006

Answer 2

41又2/3÷5/3+71又3/4÷7/4+91又4/5÷9/5
=(40+5/3)*3/5+(70+7/4)*4/7+(90+9/5)*5/9
=24+1+40+1+50+1
=117
1/5×27+3/5×41
=1/5*(27+3*41)
=1/5*(27+123)
=1/5*150
=30
5/11×1/20+3/11×1/2+5/11×1/2
=1/11*(5/20+3/2+5/2)
=1/11*(1/4+6/4+10/4)
=1/11*17*4
=17/44
59又1/2×2/3＋79又1/3×3/4+99又1/4×4/5
=(60-1/2)*2/3+(80-2/3)*3*4+(100-3*4)*4/5
=40-1/3+60-1/2+80-3/5
=180-(1/3+1/2+3/5)
=180-43/30
=178又17/30
(11又3/7+7又3/11)÷(5/7+5/11)
=(80/7+80/11)/(90/77)
=80*(7+11)/11*77*90
=16/7
1003÷1003又1003/1004+1005÷1006又1/1004
=1003÷(1003+1003/1004)+1005÷(1006+1/1004)
=1+1004+1005/1006+1005*1004
=1005^2+1005/1006

Answer 3

51又2/3÷5/3+71又3/4÷7/4+91又4/5÷9/5
= 51又2/3×3/5+71又3/4×4/7+91又4/5×5/9
= （50+5/3)×3/5+（70+7/4）×4/7+（90+9/5)×5/9
=30+1+40+1+50+1
=123
