ttyh:

What is x?


3/12, 6/9, 5/10, 7/8, 1/14, x/11

Of which they shaded 3/12, 5/10 and 1/14, seems like a pattern or something...

x = 4 ?

[ttyh]

4? what’s the rational?

ttyh:

4? what's the rational?

3/12, 5/10, 1/14

numerator + 2, denominator -2, from 3/12 to 5/10
numerator - 4, denominator + 4, from 5/10 to 1/14

6/9, 7/8, x/11

numerator + 1, denominator -1 from 6/9 to 7/8
numerator - 3, denominator +3 from 7/8 to 4/11

Complex series... :siao: right for P3?

[ttyh]

Hi

for this question, the P3s are expected to see the relation of \"numerator+denominator=15\". so, last fraction is 4/11

cheers.
