а) 1 - k = 3/5 + 1/10
1 - k = 6/10 + 1/10
1 - k = 7/10
k = 1 - 7/10 = 10/10 - 7/10
k = 3/10
1 - 3/10 = 3/5 + 1/10
б) t + 1 = 4/9 + 2/3
t + 1 = 4/9 + 6/9
t + 1 = 10/9
t = 10/9 - 1 = 10/9 - 9/9
t = 1/9
1/9 + 1 = 4/9 + 2/3
в) x + 2 3/8 = 5 1/4 - 1 3/8
x + 2 3/8 = 5 2/8 - 1 3/8 = 4 10/8 - 1 3/8
x + 2 3/8 = 3 7/8
x = 3 7/8 - 2 3/8
x = 1 4/8
1 4/8 + 2 3/8 = 5 1/4 - 1 3/8
Пошаговое объяснение:
1 - k= 3/5+ 1/10
k= 3/5+1/10+1/1
k=8/10
