b)78/150 = 13/...

c)8/11 = 88/...

d)7/15 = .../180

e)9/7 = 108/...

f)250/130 = .../13

Answer 1

Resolução!


A ) 45/60 = 9/x

45x = 9 * 60

X = 540 / 45

X = 12



45/60 = 9/12

___________________________________________



B ) 78/150 = 13/x

78x = 13 * 150

X = 1950 / 78

X = 25


78/150 = 13/25

_________________________________________________


C ) 8/11 = 88/x

8x = 11 * 88

X = 968 / 8

X = 121


8/11 = 88/121

_______________________________________________


D ) 7/15 = x/180

15x = 7 * 180

X = 1260 / 15

X = 84


7/15 = 84/180

__________________________________________


E ) 9/7 = 108/x

9x = 7 * 108

X = 756 / 9

X = 84


9/7 = 108/84


_____________________________________________


F ) 250/130 = x/13

130x = 13 * 250

X = 3250 / 130

X = 25


250/130 = 25/13

Answer 2

Resposta:

A ) 45/60 = 9/x

45x = 9 * 60

X = 540 / 45

X = 12

45/60 = 9/12

___________________________________________

B ) 78/150 = 13/x

78x = 13 * 150

X = 1950 / 78

X = 25

78/150 = 13/25

_________________________________________________

C ) 8/11 = 88/x

8x = 11 * 88

X = 968 / 8

X = 121

8/11 = 88/121

_______________________________________________

D ) 7/15 = x/180

15x = 7 * 180

X = 1260 / 15

X = 84

7/15 = 84/180

__________________________________________

E ) 9/7 = 108/x

9x = 7 * 108

X = 756 / 9

X = 84

9/7 = 108/84

_____________________________________________

F ) 250/130 = x/13

130x = 13 * 250

X = 3250 / 130

X = 25

250/130 = 25/13
