You are looking for a ratio >20. Since I didn't know the units of your two numbers, I didn't want to make false assumptions.
For sure, though, your free T3 is low. You can look at the range of your blood test, and see what values mark the upper half of the range. That's a target area. Preferably, you'd be in the top quarter of the range, but we take small steps at first. When Armour is irritating at higher doses, first consideration seems usually to be adrenal function (high/low cortisol), followed by low ferritin (want minimum 70-90, but some people need higher), low red blood cell magnesium (desirable >=6.0 mg/dl), low vit D (desirable 60-80), low B12 (desirable >800), and last, but not least, gluten intolerance.
Considerable expansion of all these issues is available on the website.
