Question

verifique se vale a propriedade fundamental das proporções nestes casos: a)2/17 =8/68 b) 28/49=/8/14 c) 20/24 =40/48

Answer 1

a)2/17 =8/68 ==> 2.68 = 17.8 ==> 136 = 136

b) 28/49=/8/14 ==> 28.14 = 8.49 ==> 392 = 392

c) 20/24 =40/48 ==> 20.48 = 24.40 ==> 960 = 960 

Answer 2

Resposta:

2/17 =8/68 ==> 2.68 = 17.8 ==> 136 = 136

28/49=/8/14 ==> 28.14 = 8.49 ==> 392 = 392

20/24 =40/48 ==> 20.48 = 24.40 ==> 960 = 960
