А) X*(828:69) = 1269 б)216 : 24*x = 9045
X = 1269 : 828/69 24*x = 216 : 9045
X = 1269/1 : 828/69 x = 216/9045 : 24/1
X = 1269 * 69 / (1 * 828) x = 216*1 / (9045*24)
X = 105,75 x = 216 / 217080 = 27/27135

в) x*(1332:74) = 1908 г) 252:36*x = 14301
x = 1908 : (1332/74) 36*x = 252 : 14301
x = 1908*74 / 1332 x = 252/14301 : 36/1
x = 106 x = 252 * 1 / (14301*36)
x = 7 / 14301
