Summary:
A complete protein is a protein source that "contains adequate proportions of the nine essential amino acids" that our body can not produce on its own.
Relatively low in protein, a single pear contains 0.5 grams of protein, or about 1% of recommended daily values. [1]
To get the adequate amount of protein with pears alone, you will need 94 pears (13890 grams) for an average female, or 113 pears for males. [4] That's over 7920 calories, and a lot of pear! Pairing pear with a richer protein source is a good idea.

Proportionally, pear does contain abundant amounts of 5 out of the nine essential amino acids. However, pear is a little short on histidine, leucine, methionine and tryptophan.[1]
To have adequate amounts of all nine essential amino acids with pear alone, you will have to eat 291 pears (43000 grams) for an average person. [2]
That's about 210% more pear to compensate for the lack of histidine, leucine, methionine and tryptophan, compared to the protein requirement alone.

Low in protein, carrot is high in histidine, leucine, methionine and tryptophan, which is complementary to pear.
A ratio of 1.7 pears (247g) and 2.5 carrots (183g) creates a complete protein profile. In fact, any ratio of more than 0.7:1 of carrot to pear will be complete.
