Question

hayar el valor de la variable que hace que se cumpla la proporcion .
a 5/10 = y/8
b 4/m = 2/11
c 14/16 = z/8
d 10/a = 20/4
e y/2 = 18/4
f 5/2 = b/4

Answer 1

Respuesta:

a ) 5/10 = y/8

5/10 = y/8

8(5) = 10y

40 = 10y

40/10 = 10y/10

4 = y

y = 4

b ) 4/m = 2/11

11(4) = 2m

44 = 2m

44/2 = 2m/2

22 = m

m = 22

c ) 14/16 = z/8

8(14) = 16z

112 = 16z

112/16 = 16z/16

7 = z

z = 7

d ) 10/a = 20/4

10/a = 20/4

4(10) = 20a

40 = 20a

40/2 = 20a/2

20 = 10a

20/10 = 10a/10

2 = a

a = 2

e ) y/2 = 18/4

4y = 2(18)

4y = 36

4y/4 = 36/4

y = 9

f ) 5/2 = b/4

4(5) = 2b

20 = 2b

20/2 = 2b/2

10 = b

b = 10
