\(\frac{11.4-11}{2-13}=\frac{11.\left(4-1\right)}{-11}=\frac{3}{-1}=-3\)

Answer 2

\(\frac{14.4-11}{2-13}=\frac{56-11}{-11}=\frac{45}{-11}\)

Answer 3

11.4/2-13=11.(4-1)/-11=11.3/-11=(-11).(-3)/-11=-3

Answer 4

\(\frac{11.4-11}{2-13}\)= \(\frac{44-11}{-11}\)= \(\frac{45}{-11}\)

Answer 5

11 . 4 - 11 / 2 - 13

=44-11/2-13

=77/2-13
