X-37цэлых 1754ых ровно15 цэлых 16 45ых

X - 37 17/54 = 15 16/45;

X = 37 17/54 + 15 16/45 = (37 * 54 + 17)/54 + (15 * 45 + 16)/45 = (1998 + 17)/54 + (675 + 16)/45 = 2015/54 + 691/45 = 5 * 2015/270 + 6 * 691/270 = 10075/270 + 4146/270 = (10075 + 4146)/270 = 14221/270 = 52 181/270.

Ответ: Х = 52 целых 181/270.
