Question

Помогите, пожалуйста!
Решите задание номер 416.

Answer 1

a) 1-k=3/5+1/10
1-k= 7/10
k=(10-7)/10 = 3/10 = 0,3

б) t+1=4/9+2/3
t= 4/9+2/3 - 9/9
t = (10-9)/9 = 1/9

в) x+2 3/8 = 5 1/4 - 1 3/8
x = 21/4 - 11/8 - 19/8
x = (42-11-19)/8 = 12/8 = 3/2 = 1,5

Answer 2

а)  1 - к = 3/5 + 1/10
1 - к = 0.6 + 0.1
к = 1 - 0.6 - 0.1 
к = 0.3

б) т + 1 = 4/9 + 2/3
т + 9/9 = 4/9 + 6/9
т = 4/9 + 6/9 - 9/9
т = 1/9

в) х + 2*3/8 = 5*1/4 - 1*3/8
х + 19/8 = 42/8 - 11/8
х = 42/8 -11/8 -19/8
х = 12/8 = 1.5
