Answer 2

Ta có:

Answer 3

\(-4\frac{1}{3}-\frac{3}{6}=-4+\frac{1}{3}-\frac{3}{6}=-4+\frac{1}{3}-\frac{1}{2}=-4-\frac{1}{6}< -4\)

=>\(-4\frac{1}{3}-\frac{3}{6}=-4\) là sai

 

Answer 4

lộn:

\(-4\frac{1}{3}-\frac{3}{6}=-\left(4+\frac{1}{3}\right)-\frac{3}{6}=-4-\frac{1}{3}-\frac{3}{6}=-4-\frac{1}{3}-\frac{1}{2}=\)\(-4-\frac{5}{6}< -4\)

=>\(-4\frac{1}{3}-\frac{3}{6}=-4\) là sai
