1-Resolva as frações a seguir:

a)5/3=8/x

b)10/16=x/36

c)3/20= 8/x

d)10/12=x/42

e)x/16=20/32

f)10/12=x/36​

Answer 1

Olá...

a)

5/3 = 8/x

5x = 24

x = 24/5

b)

10/16 = x/36

16x = 36.10

16x = 360

x = 360/16 ÷ 8

x = 45/2

c)

3/20 = 8/x

3x = 160

x = 160/3

d)

10/12 = x/42

10/12 = x/42

12x = 10.42

12x = 420

x = 420/12

x = 35

e)

x/16 = 20/32

x/16 = 20/32

32x =  16.20

32x = 320

x = 320/32

x = 10

f)

10/12 = x/36

12x = 10.36

12x = 360

x = 360/12

x = 30

Boas lições.
