Answer 1

Frações equivalentes:
A)
2/4=x/32=14/y
2/4=16/32=14/28

1/2=x/32
1/1= x/16
16=x
x=16
1/2=14/y
Y=2.14
y = 28

B)
12/6=6/x=36/y
12/6=6/3=36/18

2=6/x
1=3/x
x=3

2=36/y
1=18/y
y=18

C)
3/5=x/30=21/y
3/5=18/30=21/35

3/5=x/30
3/1=x/6
3.6= x
x= 18

3/5=21/y
1/5=7/y
Y = 5.7
Y=35

D)
4/3=x/18=36/y
4/3=24/18=36/27

4/3=x/18
4/1= x/6
4.6= x
x = 24

4/3=36/y
1/3=9/y
Y = 9.3
Y = 27

E)
15/45=3/x=y/90
15/45=3/9=30/90
1/3=3/x
X = 9

1/3=y/90
90= 3y
3y=90
Y=30

F)
3/9=21/x=y/72
3/9=21/63=24/72

1/3=21/x
X=3.21
X = 63

1/3=y/72
72=3y
3y=72
Y=72/3
Y=24
