решите уравнение 4 1/5:y=3 3/10 1/6x=8 2/3 0,5x-1/6x=2 3/10

4 1/5:y=3 3/10
y=4 1/5 : 3 3/10
y= 21/5 * 10/33
y=14/11
y=1 3/11
1/6x=8 2/3
x=8 2/3 : 1/6
x=26/3 * 6/1
x=52
0,5x-1/6x=2 3/10
1/2x-1/6x=2 3/10
3/6x-1/6x=2 3/10
2/6x=2 3/10
1/3x=2 3/10
x=2 3/10 : 1/3
x=23/10*3/1
x=6.9

1) 4 1/5:y=3 3/10
21/5 : у= 33/10
у= 21/5 : 33/10= 21/5*10/33
у=42/33= 1 9/33= 1 3/11

2) 1/6x=8 2/3
1/6х= 26/3
х= 26/3 : 1/6= 26/3*6/1
х=52

3) 0,5x-1/6x=2 3/10
5/10х - 1/6х = 23/10
30/60х - 10/60х = 138/60
20/60х = 138/60
х= 138/60 : 20/60=138/60*60/20=138/20= 6 18/20 = 6 9/10= 6,9
