Пошаговое объяснение:
₍₂₎ ₍₁₎ ₍₃₎
(8 - 2 1/7 * 3 1/9) * 27/44 = 9/11
1) 2 1/7 * 3 1/9 = (15*28)/(7*9) = (5*4)/(1*3) = 20/3 = 6 2/3
2) 8 - 6 2/3 = 7 3/3 - 6 2/3 = 1 1/3
3)1 1/3*27/44 = 4/3*27/44 = (4*27)/(3*44) = (1*9)/(1*11) = 9/11
(8-2 1/7*3 1/9)*27/44=
8-15/7*28/9)*27/44=
(8-6 2/3)*27/44=1 1/3*27/44=4/3*27/44=9/11
