Answer 1

5分之24乘8分之11+10分之61除以5分之8+10分之13乘8分之11
=24/5x11/8+61/10x5/8+13/10x11/8
=(24/5+13/10)x11/8+61/10x5/8
=61/10x11/8+61/10x5/8
=61/10x(11/8+5/8)
=61/10x2
=61/5

Answer 2

24/5×11/8+61/10÷8/5+13/10×11/8
=（24/5+13/10)×11/8+61/10×5/8
=61/10×11/8+61/10×5/8
=61/10×(11/8+5/8)
=61/10+2
=61/20

Answer 3

24/5*11/8+61/10*5/8+13/10*11/8
=1/8*(264/5+305/10+143/10)
=1/8*(528+305+143)/10
=976/80
=61/5

Answer 4

解：24/5 × 11/8 + 61/10 ÷ 8/5 +13/10 × 11/8
=(24/5+13/10)×11/8 + 61/10×5/8
=61/10×11/8+61/10×5/8
=61/10×(11/8+5/8)
=61/10×2
=61/5

Answer 5

(24/5)×（11/8)+(61/10)÷(8/5)+(13/10)×(11/8)
=(264/40)+(61/10)×(5/8)+(143/80)
=(528/80)+(305/80)+(143/80)
=976/80
=61/5
