6/9 rewrite fraction in at least 3 different ways

2/3, 12/18, 18/27. Just take the top and bottom numbers and multiply them by the same number, I used two and three. You can also divide by 3, which is how I got 2/3.

Hope this helps, let me know if you need any more help!

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
