А) 3 3/4+1 1/2=5 1/4
Б) 2 5/6- 1 5/12= 1 5/12
В) 4-1 2/3=2 1/3
Г) 3 2/7-6/7=2 3/7
Д) 1 1/3×4=5 1/3
Е) 3 1/4×2/5=1 3/10
Пошаговое объяснение:
а) 3 3/4 + 1 1/2 = 3 3/4 + 1 2/4 = 3 5/4 = 4 1/4
б) 2 5/6 - 1 5/12 = 2 10/12 - 1 5/12 = 1 5/12
в) 4 - 1 2/3 = 3 3/3 - 1 2/3 = 2 1/3
г) 3 2/7 - 6/7 = 2 9/7 - 6/7 = 2 3/7
д) 1 1/3 * 4 = 4/3 * 4 = 16/3 = 5 1/3
е) 3 1/4 * 2/5 = 13/4 * 2/5 = 26/20 = 1 3/10
