Question

помогите сделать примеры с десятичными и обыкновенными дробями

Answer 1

а) 1) 6 3/8 - 2 3/4 = 6 3/8 - 2 6/8 = 5 11/8 - 2 6/8 = 3 5/8
2) 3 5/8 * (-4) = 29/8 * (-4) = -29/2
3) 7/18 * 9 = 7/2
4) -29/2 + 7/2 = -22/2 = -11

б) 1) 4 1/3 - 8 = 4 1/3 - 7 3/3 = -3 2/3
2) 9 1/6 : (-3 2/3) = 55/6 : (-11/3) = 55/6 * (-3/11) = -5/2
3) 24 * 3/8 = 9
4) -5/2 + 9 = -2,5 + 9 = 6,5 

в) 1) 13 1/4 - 2 5/27 = 13 27/108 - 2 20/108 = 11 7/108
2) 11 7/108 - 10 5/6 = 11 7/108 - 10 90/108 = 10 115/108 - 10 90/108 = 25/108
3) 25/108 * 230,04 = 25/108 * 23004/100 = 213/4 = 53,25
4) 53,25 + 46,75 = 100
5) 100 : 0,01 = 10000
