Question

Решите Уравнение

а)1-k=3/5+1/10

б)t+1=4/9+2/3

в)х+2(целая)3/8=5(целая) 1/4 - 1(целая)3/8

Answer 1

а) 1-k = 3/5+1/10
    1-k = 7/10
     k = 1 - 7/10
     k = 3/10
б) t+1 = 4/9+2/3
    t+1 = 10/9
    t = 10/9 - 1
    t = 1/9
в) x+2(3/8) = 5(1/4) - 1(3/8)
    x+2(3/8) = 31/8
    x = 31/8 - 19/8
    x = 12/8 = 1 целая 1/2
