8 3/5 + 3,75 : (3 1/2 - 1 5/6)
= 43/5 + 375/100 : (7/2 - 11/6)
= 43/5 + 375/100 : (21/6 - 11/6)
= 43/5 + 375/100 : 10/6
= 43/5 + 375/100 x 10/6
= 43/5 + 3750/600 = 43/5 + 75/12 = 516/60 + 375/60 = 891/60 = 14 51/60
= 14 17/20

8 3/5 + 3,75 ÷ (3 1/2 - 1 5/6)

43/5 + 375/100 ÷ (7/2 - 11/6)

43/5 + 375/100 ÷ (7×6/2×6 - 11×2/6×2)

43/5 + 375/100 ÷ (42/12 - 22/12)

43/5 + 375/100 ÷ 20/12

43/5 + 375/100 × 12/20

43/5 + 375×12/100×20

43/5 + 4.500/2.000

43×2.000/5×2.000 + 4.500×5/2.000×5

86.000/10.000 + 22.500/10.000

108.500÷100/10.000÷100
