Найдите корень уравнения (0.988+x) * 2.5=4.87

11.2: (х+2/15=6

(х+8/27) : 19 целых5/9=1/12

(0.988+x) * 2.5=4.87

0,988+x=1,948

x=1,948-0,988

x=0,96

11.2: (х+2/15) = 6

x+2/15 = 11,2:6

x+2/15 = 1 13/15

x = 1 13/15 - 2/15

x = 1 11/15

(х+8/27) : 19 целых5/9=1/12

x+8/27 = 1/12 * 19 5/9

x+8/27 = 1/12 * 176/9

x+8/27 = 44/27

x=44/27 - 8/27

x=36/27

x = 1 целая1/3
