Answer 1

1) 1 1/3x+0.2=1
1 1/3x=1-0.2
1 1/3x=0.8
x=0.8:1 1/3=8/10:4/3=4/5*3/4
x=3/5
2) 3/25y-1.2=0.6
3/25y=0.6+1.2
3/25y=1.8       3/25=0.12
0.12y=1.8
y=1.8:0.12
y=15
3) 1.32x+4=10 3/5           10 3/5=10.6
1.32x+4=10.6
1.32x=10.6-4
1.32x=6.6
x=6.6:1.32
x=5

Answer 2

1) 1⅓х=1-0.2
4/3 х=0.8
х = 8/10 × 3/4
х = 24/40
х = 4/5
2)3/25у=1 8/10
y= 6/1×25/3
у= 50/1
у= 50
