Решите уравнение 8/27+m=17/27 n+1/8=3/8 1/3+n=5/12. m+1/4=2/3. n+1/25=2/5. 2/13+m=3/5

Вычислим неизвестные.

1) 8/27 + m = 17/27;

m = 17/27 - 8/27;

m = (17 - 8) / 27;

m = 19/27.

2) n + 1/8 = 3/8;

n = 3/8 - 1/8;

n = (3 - 1) / 8;

n = 2/8;

n = 1/4.

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

n = 5/12 - 1/3;

n = 5/12 - 4/12;

n = 1/12.

4) m + 1/4 = 2/3;

m = 2/3 - 1/4;

m = 2 * 4/12 - 1 * 3/12;

m = 8/12 - 3/12;

m = 5/12.

5) n + 1/25 = 2/5;

n = 2/5 - 1/25;

n = 2 * 5/25 - 1/25;

n = 10/25 - 1/25;

n = 9/25.

6) 2/13 + m = 3/5;

m = 3/5 - 2/13;

m = 3 * 13/65 - 2 * 5/65;

m = 39/65 - 10/65;

n = 29/65.
