Chi squared test

I have six ratios (females-males). These are the observed values:

1.78 - 1.17 - 0.53 - 1 - 0.85 - 0.56

I expect all these ratios to be equal. But as for the “equal” value, there is no expectation. It could be any value, providing that this value is the same for all the cases. How can I run a Chi test in this condition? What do I plug into the “expected value” of the formula? Thanks
