Answer:

1.Option D

2.Option B

3.Option D

Step-by-step explanation:

1.We are given that 1\frac{1}{3}+2\frac{3}{4}

We have add and simplify

\frac{4}{3}+\frac{11}{4}

1\frac{1}{3}+2\frac{3}{4}=\frac{16+33}{12}

1\frac{1}{3}+2\frac{3}{4}=\frac{49}{12}

1\frac{1}{3}+2\frac{3}{4}=\frac{49}{12}

Hence, Option D is true.

2.We are given that 11\frac{1}{12}-2\frac{2}{3}

We have to subtract and simplify

\frac{133}{12}-\frac{8}{3}

=\frac{133-32}{12}

=\frac{101}{12}

8\frac{5}{12}

Hence,option B is true.

3.We are given that 1\frac{3}{12}\cdot 2\frac{2}{3}

We have to multiply and simplify

\frac{15}{12}\cdot\frac{8}{3}

=\frac{5}{12}\cdot 8

=\frac{10}{3}

=3\frac{1}{3}

Hence, option D is true.
