Найдите корень уравнения: d+1/3=5/12 y-2/9=7/18 4/15+m=5/12

1) d + 1/3 = 5/12;

d = 5/12 - 1/3 = 5/12 - 4/(3 * 4) = 5/12 - 4/12 = (5 - 4)/12 = 1/12;

Ответ: d = 1/12.

2) y - 2/9 = 7/18;

у = 7/18 + 2/9 = 7/18 + (2 * 2)/(9 * 2) = 7/18 + 4/18 = (7 + 4)/18 = 11/18;

Ответ: у = 11/18.

3) 4/15 + m = 5/12;

m = 5/12 - 4/15 = 5 * 5/(12 * 5) - 4 * 4/(15 * 4) = 25/60 - 16/60 = (25 - 16)/60 = 9/60 = 3/20;

Ответ: m = 3/20.
