Answer 1

Answer:

$\frac{11}{15}-\frac{2}{3}\left(-0.4\right)-\frac{4}{3}=-0.33333\dots$

Step-by-step explanation:

m + np - q

$\frac{11}{15}-\frac{2}{3}\left(-0.4\right)-\frac{4}{3}$

$\frac{11}{15}-\frac{2}{3}\left(-0.4\right)-\frac{4}{3}$

$0.4\cdot \frac{2}{3}-\frac{4}{3}+\frac{11}{15}$

$=0.26666\dots -\frac{4}{3}+\frac{11}{15}$

$=-\frac{20}{15}+\frac{11}{15}$

$=\frac{-20+11}{15}$

$=-\frac{9}{15}$

$=0.26666\dots -\frac{3}{5}$

$=-0.33333\dots$
