Answer 1

а) 21/10 + 4/15 = 63/30 + 8/30 = 71/30 = 2 целые 11/30

б) 36/5 - 7103/1000 = 7200/1000 - 7103/1000 = 97/1000 = 0.097

в) 222/10 : 37/7 - 13/5 = 42/10 - 26/10 = 16/10 = 1.6

г) (28/10 * 17/100 * 28/10) / (17/10 * 82/10 * 28/100) = 14/41

д) 4/19 * 26/10 - 12/5 * 4/19 = 4/19 * (13/5-12/5) = 4/19 * 1/5 = 4/95
