Answer:

1 plant

Step-by-step explanation:

The T.Rex dinosaur eats ten twelffths of a plant and later eats two twelfths of a plant. In total, the T.Rex dinosaur ate:

[tex]\frac{10}{12} + \frac{2}{12} =\frac{12}{12}=1[/tex]

Therefore, the dinsaur in total ate one entire plant.

It's better to solve the problem by using fractions instead of decimals. If we had used decimals the response would be the following:

[tex]0.833333+0.166666=0.999999[/tex] which can be rounded to 1.
