Select all of the ratios that are equivalent to 6:16. A. 2:8

B. 3:8

C. 12/18

D. 30/80

Answer : B, D

Step - by - step explanation :

6/16 Divided by 2/2 --> 3/8 ( so it's not 2/8 )

6/16 Multiplied by 2/2 --> 12/32 ( so it's not 12/18 )

30/80 --> 3.75 6/16 --> 3.75

First, simply 6:16 to 3:8.

Now, choose ratios from there.

B) is 3:8 so that one works.

D) works also, because you just multiply each side by 10.

B and D

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

i pretty sure it is
