Пошаговое объяснение:
750.
1) 17/600 = 17/(2*2*2*3*5*5),
2) 14/125 = 14/(5*5*5) = 0,112,
3) 17/200 = 17/(2*2*2*5*5) = 0,085,
4) 51/105 = 51/(3*5*7),
5) 31/500 = 31/(2*2*5*5*5) = 0,062,
6) 11/150 = 11/(2*3*5*5)
751.
1) 7 / (2² * 5²) = 7 / (4 * 25) = 7/100 = 0,07,
2) 13 / (2² * 5²) = 13 / (4 * 25) = 13/100 = 0,13,
3) 21 / (2³ * 5³) = 21 / (8 * 125) = 21/1000 = 0,021,
4) 57 / (2² * 5²) = 57 / (4 * 25) = 57/100 = 0,57
