In this illustration, England could commit 100 hours of labor to produce one unit of cloth, or produce units of wine. Meanwhile, in comparison, Portugal could commit 100 hours of labor to produce units of cloth, or produce units of wine. Portugal possesses an absolute advantage in producing both cloth and wine due to more produced per hour (since > 1). If the capital and labour were mobile, both wine and cloth should be made in Portugal, with the capital and labour of England removed there. If they were not mobile, as Ricardo believed them to be generally, then England's comparative advantage (due to lower opportunity cost) in producing cloth means that it has an incentive to produce more of that good which is relatively cheaper for them to produce than the other—assuming they have an advantageous opportunity to trade in the marketplace for the other more difficult to produce good.
