Ответ : 6 км/ч
23 / (6 5/17 + 1 12/17) - (4 2/5 - 2 3/5) / 5
1) 6 5/17 + 1 12/17 = 6 + 1 + (5/17 + 12/17) = 7 + (17/17) = 7 + 1 = 8
2) 4 2/5 - 2 3/5 = 1 + (7/5 - 3/5) = 1 + 4/5 = 1 4/5
3) 23 / 8 = 23/8
4) 1 4/5 / 5 = 9/5 / 5 = 9/25
5 23/8 - 9/25 = 575/200 - 72/200 =503//200 = 2 103/200
12 = 2^2*3; 14 = 2*7; 42 = 2*3*7; НОК = 2^2*3*7 = 12*7 = 84
168 = 2^3*3*7; 252 = 2^2*3^2*7; НОК = 2^3*3^2*7 = 8*9*7 = 504
504 > 84
Ответ:да
Пошаговое объяснение:500*3=1500
