№ 1. 36/25 : (-0,3) = - 4,8
36/25 : (-3/10) = 36/25 * (-10/3) = (-120/25) = - 4,8
№ 2. 3/14 : (-3,7 + 40/7) = 5/47
1) -37/10 + 40/7 = (-259/70 + 400/70) = 141/70
2) 3/14 : 141/70 = 3/14 * 70/141 = 5/47
№ 3. (0,6 - 4,7) : (2 1/7 - 3 4/9) = 3,15
1) 0,6 - 4,7 = -4,1
2) 15/7 - 31/9 = 135/63 - 217/63 = -82/63
3) -4,1 : (-82/63) = -41/10 * (-63/82) = 63/20 = 3,15
